As renewable and distributed generation proliferates on the global electricity network, conventional protection and automation methods begin to lose their selectivity as fault characteristics change. Fortunately, the reduction of fault magnitude and complexity of power flow can be handled by distribution automatic circuit reclosers such as Noja Power’s OSM recloser, enabled by the implementation of […]
For the safety of personnel and assets, the importance of the integrity of the substation earth mat and lightening protection should not be underestimated. It is recommended that these are tested during annual substation maintenance. The Gossen MetraWatt Geohm series is capable of much more than just easy and reliable implementation of the most common […]
The Kathu Solar Park, which was constructed by Sener and Acciona Industrial, came into commercial operation recently. With an installed capacity of 100 MW, it will allow clean energy to be supplied to 179 000 homes in the Northern Cape Province and prevent the emission of 6-million t CO2 into the atmosphere over the next […]
Trafo Power Solutions has secured the order for 13 custom-designed cast resin transformers for Rand Water’s large Zuikerbosch wastewater treatment works near Vereeniging. The water purification and sedimentation facilities at Zuikerbosch will reportedly provide an additional 600 Ml per day to the system at a project value of R3-billion, as part of efforts to meet growing […]
Local manufacturing company RWW Engineering has been awarded a five year supply contract from Eskom for 22 kV and 33 kV auto-reclosers. The company will supply the Noja Power range of reclosers. Local manufacture, assembly and wiring of the control panels, together with factory testing of the completed units, will ensure that Eskom receives reliable and […]
HV Test offers DV Power’s first handheld micro ohmmeter which generates regulated DC current up to 300 A. The RMO-H is ideal for a number of applications for contact resistance measurements of non-inductive test objects in both field and factory testing environments, with a user-friendly interface, allowing the user to set and start a preferred test […]
Schneider Electric has released the TeSys GV4 multifunction mobile app that connects to its new TeSys GV4 motor circuit breaker to provide basic and advanced protection settings configuration using near field communication (NFC) interface. The technology of the GV4 compact and robust motor circuit breakers offers advanced protection with ratings up to 115 A with service […]
The new hagercad software from Hager for planning and configuration of low-voltage switchgear is now available locally from ElectroMechanica (EM), Hager’s official distributor in South Africa. The software package is aimed at the design and encryption of distribution boards up to 4000 A. A major feature is the automatic circuit diagram function. This means that hagercad can […]
Electrical protection engineering has a list of favourite features which are commonly applied in distribution networks. Features such as overcurrent and conventional earth fault are ubiquitous in network protection assets, but a new list of protection capabilities is now available. Three less commonly applied protection elements which feature in the OSM Recloser system, are available […]
