New cable and pipe locator

provides instant push-button depth up to 7,6 metres and current measurement to help identify target utilities in crowded easements. Enquiries:Tel. 010 595 1831 or email sales@instrotech.co.za

Built on a proven design, and with Pathfinder SAF Technology at its core, the 8879v3 offers RYCOM’s most advanced signal acqui- sition and filtering technology.The 8879v3 cable and pipe locator offers a utility locator FrequencyFlex allowing users to adapt the system to their specific needs. Multiple active frequencies allow the user to accurately locate the cable and / or pipe with minimum interference and maintain the ability to continue locating past faults and around conduit bends. Passive frequencies identify ‘live’ and charged lines by their naturally occurring electromagnetic fields. The 8879v3 offers multiple passive frequencies – 50 Hz, 60 Hz, Radio Frequency, Cathodic Protection Rectifier and CATV allowing line locating without the use of a transmitter. Updated transmitter functions include improved transmitter induction, multi-frequency coupled induction ranging from 8 kHz to 118 kHz, and automatic impedance matching for direct connec- tions.The 5W or 10W transmitter has the ability to simultaneously apply two frequencies to a utility. From one transmitter setting the user can locate the main line as well as other services by ‘lighting up’ the entire site. This set-and-forget feature streamlines opera- tion by reducing the need to repeatedly relocate the transmitter. All functions are accessed via weather-proof membrane buttons and both user input and transmitter status are verified with audible re- sponses.The ergonomically designed and balanced 8879v3 receiver

Leak-detection in coal-fired power stations Instrotech - a Comtest Group Company - has de- signed and developed at the request of and, in consultation with the South African Power Utility (where 93% of all electricity is currently generated using coal) an advanced acoustic leak detection system called Inspecta FFT, to detect boiler tube leaks in coal fired utilities as well as in oxygen plants and gasifiers. This technology and equipment is now in use in power stations worldwide, where the early detection of tube leaks to reduce down time and prevent con- sequential damage is vital. According to the World Coal Association, the importance of coal to electricity generation worldwide is set to continue, with coal fueling 44% of global electricity in 2030. (Source IEA 2010). The Inspecta installed base includes power stations in

Repair contracts from Sasol ActomGroup division, Marthinusen & Coutts has secured three separate contracts from SASOL for the repair of low voltage motors, the repair of medium voltage motors up to 1 MW and the repair of medium voltage motors from 1 to 5 MW. According to Richard Botton, managing director of Marthinusen & Coutts , the company is known for its technical ability and the provision of a superior quality and technical service, and the award of these contracts is testament to its extensive capabilities. “Marthinusen & Coutts has worked with SASOL for many years and is regarded by the organisation as a highly competent and technically qualified OEM repairer.”

The company underwent a lengthy prequalification stage whereafter its fa- cilities in Cleveland were audited for quality, as well as technical capability and capacity. “Our ability to comply with SASOL’s de- manding specifications and to render complex repairs in accordance with the necessary quality was a big differentiator for us.
