Power Factor Correction solutions from ACDC Dynamics

this great product from its Entes Range.

Network Analysers are designed to measure all electrical parameters of the networks in indus- trial plants. MPR-4X series network analysers can be customised for various applications with I/O modules. • Power factor controllers: Reactive Power Fac- tor Controllers try to match the system’s power factor, which is defined as the ratio of the active power to the apparent power to the user-defined power factor value. ACDC Dynamics strives to drive down electricity costs for its customers by helping households and businesses to be more energy-saving efficient with

ACDC Dynamics has long been a market leader in the field of Power Factor Correction. The simple ex- planation of this is the difference between applied load and actual consumed power which is meas- ured at a value from 0 to 1 where a value of 1 is per- fectly correct for 100% power saving. The technical cause is the present load of inductive equipment. There is a long list of basic formulas that can be done, but it comes down to the voltage-current and the magnetic current being out of phase; when both are in phase, Power Factor Correction comes down to a value of 1. The technique used is to add capacitance via ca-

pacitor banks to improve the voltage current. The largest factor of the inductive load is mostly electric motors consisting of winding that draw current and then cause constant inductive load. ACDC Dynamic has some great products from its Entes range to assist customers and electrical con- tractors with all their energy management require- ments. Entes is a leading European technology com- pany specialising in energy management products that will help you save on electricity costs. Here are some of the products that ACDC Dy- namic has in its Entes range to assist its customers: • Network Analysers: Entes MPR and EPM series

T he Standards Division of the South African Bureau of Standards (SABS) maintains and develops several national standards aimed at ensuring the protection of life and property from fire and fire-related damage. As part of this legislated mandate the SABS has recently published a revised version of SANS 10139, Code of practice for design, installation, commission- ing and maintenance of fire detection and alarm sys- tems in non-domestic premises which brings South Africa in line with fire safety standards similar to those in the United Kingdom and Europe. The standard provides recommendations for the planning, design, installation, commissioning and maintenance of fire detection and fire alarm systems in and around buildings, other than dwellings. SANS 10139 is based on the British Standard BS5839-1, Fire detection and fire alarm systems for buildings. Code of practice for design, installation, commissioning and maintenance of systems in non- domestic premises. The British Standard (BS5839- 1) was updated several years ago after fatalities oc- curred at an old age home in Lancashire that killed 14 elderly people. This revised South African National Standards (SANS) comes at a time when the country witnessed two devastating fires. The seriousness of fire is often overlooked, and their impact is often underestimated. It is crucial that a national set of guidelines and rules for the design- ers and installers of fire protection systems is pro- vided for them to follow and uphold. The costs of fire within this country runs into the billions of Rands and needs to be prevented. SABS updates national standard on crucial fire detection and alarm systems
