SA’S GREEN ENERGY OUTLOOK FOR 2022

W ith a background in electrical engineering, a knack for busi- ness, and a passion for sustainability, Jan Fourie has special- ised in renewable energy projects for over a decade. Currently serving as Southern Africa General Manager for Norwe- gian global renewables giants, Scatec, Fourie’s career began as a con- sultant for Koeberg, SA’s flagship nuclear power station, an experience which sparked his attraction for large-scale power generation and in- frastructure projects. Fourie’s natural flair and passion for business became apparent while working in this space, and he augmented his technical qualification in electrical engineering with solid busi- ness credentials in the form of an MBA from the Graduate School of Business at UCT. Fourie’s love for South Africa and the natural environment, the landscapes and the flora and fauna, is core to his passion for sus- tainability and his current role at Scatec perfectly encapsulates his three-pronged passions for sustainability, business, and the techni- cal side of large-scale power generation. “Being part of an industry that accomplishes power generation, decarbonization, and job crea- tion is a very fulfilling pursuit. We give power to the people on many levels. I get up excited for work, and I’m proud to tell my children about what we do at Scatec,” he says. Noting the devastation in the nation’s coal belt, Emalahleni (for- merly Witbank) and surrounds, where 5000 people perish every year due to lung diseases, and where childhood asthma is rife, Fou- rie says that, “the need for cleaner energy in SA is urgent”. “Nevertheless, the mines and coal-fired power stations are the lifeblood of many communities, and to abandon them would re- sult in a landscape of ghost towns, and a human tragedy of mass unemployment. I therefore fully support the DMREs’ plan to repur- pose these areas, preferably by retrofitting existing coal-fired plants with renewable energy plants and/or battery storage solutions, and training people in new skills to ensure that jobs can be transferred,” says Fourie. He says that the COP26 conference, which took place in Glas- gow last month, could herald solutions to some of Eskom’s woes. “The Paris Climate Agreement of 2016 acknowledges the duty of developed nations, who are responsible for the bulk of green- house gases emitted thus far, to assist developing nations in their efforts to decarbonise, and mitigate risks associated with climate-

change,” says Fourie. “In what President Ramaphosa has called a ‘watershed moment’, at COP26 a coalition of developed nations (the EU, France, Germany, the UK and the USA), committed ZAR 131 billion to help SA - currently the conti- nent’s biggest polluter, and 12th biggest globally – to affect a just, inclusive energy transition”.

New app paving the way for tradespeople

TOD’s newly-released, free-to-download HERO app ensures that, for tradespeople and their clients, those ‘life happens’ moments are taken care of instantaneously. It’s a one-stop business management tool in the pocket of on-call trade specialists, ensur- ing a smoother working life and, most importantly, more job requests. “The TOD Hero app really is like an Uber for people who need plumbers, handymen, locksmiths and electricians in real time,” says TOD CEO & Founder Shannon Mackrill. “Lockdown left a lot of tradespeople without work and many smaller companies had to shut down, even though geysers kept bursting and homes still needed fixing. “In other words, the work was still there but smaller operators didn’t have access to market and thus they could not connect with customers needing their services,” Mackrill adds. “TOD wants to be the voice of small businesses and entrepreneurs, by offering them access to market via our business management tool. We provide cred- ibility and, in so doing, help them grow their businesses.” New business management features in the app prioritise simplicity, direct connec- tion and cashless payment. Now tradespeople can email personal job quotes, get them approved, generate invoices and send them to clients, all in-app. The same holds true for diary management of TOD jobs, private work and reminders, thereby syncing perfectly into a brilliant and intuitive diary management tool that now also allows clients to book your services at a later date. The new app now also includes add-ons including GPS tracking, photo sharing, detailed job card descriptions, tool suggestions and an in-app chat function, thereby making preparing for jobs easier than ever. Mackrill says the aim of the TOD HERO platform is to provide work and opportuni- ties for tradespeople, with an innovative tool to conduct and manage back-office work. “The vision behind TOD is simple,” says Mackrill. “We care about our tradespeople and so have come up with an app that spreads the love. At its heart, it connects

customers to credible tradespeople based in Cape Town, Johan- nesburg, Pretoria, Port Elizabeth, Bloemfontein and Durban, on- demand or at a future date, 24/7/365. Add to that TOD’s ability to develop and manage the world’s largest connected tradesperson workforce, and what you have is a powerful tool to empower indi- viduals to manage and grow their own businesses.” The reimagined HERO app is the result of years of extensive research aimed at understanding what Mackrill calls tradespeo- ple’s “pain points” and how they relate to customer needs. Col- laboration with companies such as Vodacom and Builders has ensured credibility and is helping to achieve the company’s aim of capturing a large percentage of tradespersons operating in South Africa. TOD is an app that connects users to credible tradespeople (plumbers, electricians, handymen, locksmiths, etc.) on-demand or at a future date, 24/7/365, based on location and availability. The entire process is managed in-app from door-to-door tracking to quoting and finally easy cashless payment and invoice.

The do's and don'ts of email etiquette W hen the use of email became common in the early 90s, the business world changed. Email now takes up a significant por- tion of our workday. While we try to work faster and more ef- ficiently, we must not forget the social rules that accompany any form of communication. Here are some of the do's and don’ts of email etiquette. Do have a clear subject line Most of us have to compete with the hundreds of emails clogging our inbox every day, so the clearer your subject line, the more likely your mes- sage will be read. For example, if you’re sending a proposal to someone, be specific and write, “The Electrical Proposal Is Attached.” Do use a professional salutation Using “Hey,” “Yo,” or “Hiya” isn’t professional, no matter how well you know the recipient. Use “Hello” instead. To be more formal, use “Dear”. Using the person’s name, “Hello Robert”, is quite appropriate, but remember not to shorten a person's name unless you have been given permission to do so.

Don't forget your signature Every email should include a signature that tells the recipient who you are and how to contact you. Set it up to automatically appear at the end of each email. Include all of your contact details so the recipient doesn’t have to look up your address, email or phone number. Do proofread your message Don't be surprised if you're judged by the way you compose an email. For example, if your email is littered with misspelled words and grammatical errors, you may be perceived as sloppy, careless, or even uneducated. Check your spelling, grammar and message before hitting 'send.' Don't use humour Humour does not translate well via email. What you think is funny has a good chance of being misinterpreted by the other party, or taken as sar- casm, without the accompanying vocal tone and facial expressions. When in doubt, leave humour out of business communications.

Dangerous claims about flameproof junction boxes for use in Zone 0 applications

I n the December issue of this publication the author of an article about Flameproof Junction Boxes made a series of incorrect and misleading statements. The author also made an incorrect claim about the suitability of installing an Ex d flameproof enclosure with Ex e terminals in a Zone 0 area. If any installers believed the claims and installed the product accordingly then they would, at the least, be negli- gent of their obligations for installing electrical equipment in hazardous areas and most likely criminally responsible for any resulting explosion and loss of life. The claim was that by installing Ex e terminals inside an Ex d junction box, the installer would achieve the two levels of independent Ex protec- tion required for a Zone 0 installation. This erroneous claim is wrong. The actual wording of the claim made was: “However, with the inclu- sion of increased-safety terminals inside a flameproof enclosure, the terminations rating is pushed up to Zone 0 (two independent levels of protection via EPL Gb, per SANS/IEC 60079-14/26) meaning it can now be installed in an environment where there is a constant hazard”. The important words to take note of are “two independent levels of pro- tection.” It seems the author is not familiar with the certification of his own company’s products. The certification of any Ex e terminal (including the author's own terminals) always contains the following words in its Schedule of Limitation: - “The terminals may only be used inside a pre- viously approved Ex enclosure with a minimum IP rating of IP54.” This means quite clearly that the terminals only become certified Ex e when they are inside a suitable Ex enclosure (usually Ex e) and put- ting them inside an Ex d enclosure with an IP rating of IP54 or better would satisfy this requirement. However, this does not make the level of protection provided by the Ex e terminals independent of the Ex d pro- tection provided by the enclosure as they depend directly upon the Ex d enclosure for ingress protection and protection against impact in order for the terminals to achieve their Ex e certification. The combination of any Ex d enclosure with any Ex e terminals will therefore only provide one level of protection, not the two independent levels of protection required for Zone 0 use as claimed by the author. If further proof is needed, the certification number of the author's own Ex e terminals ends with the letter ‘U’. This means that these terminals are certified only as components and therefore must be re-assessed as part of an Ex assembly. To quote IEC 60079-0 “The symbol “U” is used to identify that the equipment is incomplete and is not suit- able for installation without further evaluation.” This is hardly the lan- guage used of a product providing an independent level of protection and is in complete conflict with the author's advice. Unfortunately, the author of the article does not seem to know these quite basic facts and compounded the earlier incorrect statements by adding the following dangerous statement: - “The important part to remember, if you are advising anyone on such an installation, is that this termination is now suitable for Zone 0 appli- cations, with minimal additional consideration.” My response to this is twofold. Firstly, if you are giving advice about a Zone 0 installations then you should really know the Ex Standards and what is required (and so should the person specifying the installation). The specifier should also examine the certification of the products being

used in such a safety-critical application. SANS/IEC 60079-14 clause 4 states: “It is necessary to ensure that any installation complies with the relevant equipment certificate as well as with this standard and any other requirements specific to the plant on which the installation takes place.” Secondly, the author's additional words “with minimal additional con- sideration” sounds like a legal escape clause. When it comes to install- ing electrical equipment in Zone-0 or in any zone for that matter, there are many “additional considerations.” SANS /IEC 60079-14 Scope states: Where the equipment is re- quired to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional protec- tion requirements may be necessary.” In clause 4 the standard goes on to say “Consideration should be given to obtaining information for maintenance and repair to meet the requirements of IEC 60079-17 and IEC 60079-19 respectively.” “- documentation relating to the suitability of the equipment for the area and environment to which it will be exposed, e.g., temperature rat- ings, type of protection, IP rating, corrosion resistance;” Clause 5.9 of the standard says “Electrical equipment shall be se- lected and/or installed so that it is protected against external influences which could adversely affect the explosion protection.” And lists corro- sion, chemicals, condensation and moisture as some of the influences to consider. The specifier /installer must consider the effects of the hazardous gases or vapours on the integrity of the installation with regards to the performance of the flame path, the IP seals and the terminals them- selves. (Such as evidenced in the photos of a similar failed Junction box that was installed in a Zone -1 area.) Flameproof junction boxes made out of cast iron are highly suscep- tible to corrosion especially if their flame paths are unprotected. On the other hand, good quality Ex d flameproof junction boxes would have their critical flame paths treated with a metallurgical process that resists corrosion. In addition, they would have IP seals made from hydrocar- bon resistant polymers that seal on the outer rim of the flame path which give additional protection to the flame path from corrosion. They would also have captive high tensile stainless-steel screws which would not get lost at the time of installation. Unlike zinc coated steel fasten- ers, high tensile stainless-steel fasteners would not weaken over time due to corrosion which is critical as the fasteners need to secure the lid against explosive pressure for the lifetime of the installation. Such good quality Junction boxes would also have been independently tested for resistance to environmental corrosion to ASTM B117-03 and ISO 6988 standards. Another important consideration is the fact that an installation in a Zone 0 environment could suffer from the risk of an explosive gas mix- ture (which is always present or present for long periods) or liquid mi- grating through the interstices of a cable to an area with a lower level of Ex protection, leading to an explosion. (Sceptics may think that this can- not happen, but the infamous Torrens Island explosion shows that this does happen even when only in Zone 1 in which an explosive mixture is only present for a relatively short period compared to Zone 0 where it is always present). SANS/IEC 60079-14 clauses 9.3.2 and 10.6.2 are clear on how to address this risk. In summary, the installer or specifier of Ex equipment should not be taking dangerous, second-hand subjective advice from a manufacturer but should objectively read the certificates and the installation standards and should certainly not believe that putting

Obituary: Aad van Oosten 1941 – 2021

M embers of the electrical fraternity in the Western Cape were saddened to learn of the passing of a past Ray- chem colleague, mentor and friend, on 8 De- cember, following his death of natural causes. Van Oosten was born, raised and received his schooling in the Netherlands, and graduat- ed with a B.Sc. in electrical engineering. After graduation, he immediately joined Raychem Netherlands as a technical service engineer, starting in the Electronics Division, before joining the Chemelex electric polymer heater tape division. Van Oosten eventually found his niche in the medium and high-voltage ca- ble accessories domain and transferred to the Power Division. Here he would qualify himself as an international expert in the manufactur- ing, testing and application of high-voltage heat shrinkable cable accessories, globally. Van Oosten is well known to the South Af- rican electrical fraternity, through his personal contact, presentations and lectures on diverse forums throughout the country. To this end, he

fect of cable damage under load conditions was highly sort after, and his findings and rec- ommendations were accredited at the highest electrical engineering levels. During his tenure at Raychem, Van Oosten made many visits to South Africa, and devel- oped a love for the way of life and the people of this country. On his retirement in 1999, he located to South Africa from Germany and settled down in the Sun Valley area of the Cape Peninsula. However, he was quickly picked up by Tank Industries (Pty) Ltd, and appointed manager of the Power Division. His experience and knowledge of electrical power cable accessories contributed much to the growth and success of Tank Power Division. His passing this week will leave a huge gap in the electrical cable industry. He leaves a phenomenal legacy to the electrical engineer- ing fraternity, for which he will be remembered. On behalf of the Tank Industries Team, may he rest in peace. By Dr. Alan Nelson, Tank industries

WearCheck embraces communication tech

O ne of the latest technological innovations employed by conditionmonitoring specialists WearCheck is enabling the company’s sophisticated online system to send customers their reports via WhatsApp. Managing director Neil Robinson says WearCheck is constantly exploring how technology can enhance the customer experience as well as continuously improving condition monitoring techniques. WearCheck’s IT manager Eddie Perumal explains how it works: “WhatsApp has proven its convenience as an integral part of everyone’s daily life, and it adds value by allowing us to communicate in real- time with maintenance teams who may be on the factory floor with their mobile phone, rather than waiting until they are sitting behind a desk checking emails. Therefore, we felt it was fitting to incorporate the option of communicating with our customers via WhatsApp,” he says. Customers can select from three message options – one-page report; two-page report, or status. Reports include fleet information, problem type and diagnosis. This feature applies to critical and urgent samples. Another powerful reporting tool is WearCheck Online, a web-based system which allows customers to view their sample report and fleet information, as well as submit their sample registration details and feedback.

Zest WEG is key supplier of motors and VSDs for Kamoa-Kakula

The first phase order included over 700 WEG low voltage IE3 premium efficiency motors, supplied to various local and international original equipment manufacturers, and installed throughout the concentrator plant. These motors drive equipment such as the rock breakers, conveyor drives, flotation cells, thickeners, slurry pumps, winches and other mechanical OEM packages. Where processes within the plant required variable speed control, WEG low voltage VSDs were selected to provide the speed and control necessary for this equipment. Martins explains that by selecting WEG low voltage VSDs in combination with WEG low voltage motors, Kamoa-Kakula will benefit from a 36 month warranty period. “An important part of the energy efficiency strategy was for the plant to standardise on our IE3 premium efficiency motors – rated according to the IEC 60034-30 international standard,” he says. “With a class leading energy efficiency rating, this means reduced carbon emissions and greatly reduces operational energy costs.” Additionally, Zest WEG is supplying the Kamoa-Kakula Project with a new 20MVA, 33kV/11kVmobile substation, which is currently beingmanufactured in South Africa. The substation will provide stepped down power, and can be moved to supply power to different areas within Kamoa-Kakula’s mining footprint. “Underpinning the performance of our equipment at the mine will be high levels of service and support from Panaco who is our Value Added Reseller (VAR) in the DRC,” says Martins. Commenting on VARs, Martins says that those appointed by Zest WEG in this role are far more than simply distributors. “Panaco, as our VAR in the DRC, is a 100% locally owned business specifically chosen to promote and support the wide range of Zest WEG’s offering in the region. Its team includes technical specialists and the company’s operating methodologies and culture are closely aligned with ours, and will aid in supporting our current installed base, client network and growth expectations in the region.”

Zest WEG is supplying an extensive range of motors and variable speed drives (VSDs) for the second phase of the Kamoa-Kakula project, one of the world’s most exciting new copper developments, located on the Central Afri- can Copperbelt in the DRC. Phase one produced its first copper concentrate on 25 May 2021, and is expected to produce 200 000 tonnes of copper in concentrate annually. Phase 2, now in the advanced stages of construction, will result in a doubling of production capacity. Future phased expansions will eventually see a mining rate set to process 19 million tonnes per annum. For the first phase of the project, Zest WEG was also the key supplier for this electrical equipment. According to Joe Martins, mining sector specialist for Zest WEG, the mine’s scope of supply for the second phase is a repeat of the first. The first phase was supplied in 2020 with WEG medium voltage VSDs and WEG high voltage motors to drive the mine’s primary and secondary mills in the concentrator plant. “We began to manufacture these long lead time items in 2019, and delivered two medium voltage VSDs and two 3,3 kV motors for the mine’s 7,000 kW primary ball mill and its 7 000 kW secondary mill,” says Martins. “Our high voltage motors and medium voltage VSDs were also selected to drive the two 1 200 kW high pressure grinding rolls (HPGRs) in the plant.” WEG high voltage motors and automation solutions drive the underground ventilation fan applications, providing fresh air to the underground mine workings, he says. All these large items are designed to specification, manufactured and tested in WEG’s Brazil facilities. Due to Covid-19 travel restrictions, the factory acceptance tests were conducted virtually, with special processes being developed to allow thorough inspection and comment online. The testing of the equipment for phase two – also conducted in a virtual environment – was completed in the third quarter of 2021. Significantly, Kamoa-Kakula will be among the world's lowest greenhouse gas emitters per unit of copper produced, and Zest WEG’s energy efficient motors and automation solutions will contribute to this.
