Deployment of the g3 gas mixture as a replacement for gaz sf6 has taken a major step forward: the F35-145 kV gas-insulated substation (GIS) is now gaz sf6-free too. It has the same physical footprint as its gaz sf6-based GIS predecessor and can operate at ambient temperatures as low as -25 °C.Get price

Large consumers of electricity are invariably supplied at HV. On LV systems operating at 120/208 V (3-phase 4-wires), a load of 50 kVA might be considered to be “large”, while on a 240/415 V 3-phase system a “large” consumer could have a load in excess of 100 kVA. Both systems of LV distribution are common in many parts of the world.Get price
