Page 8: The Need For Earth Leakage Protection
Cable construction is such as to provide every phase conductor with an individual conductor screen so that crushing would cause a low single phase to earth fault current. The protective device, such as an Ampcontrol ELD earth leakage relay, would then isolate the cable and contain the sparking within the cable before a heavy short circuit current due to a phase to phase fault occurs. -
Page 9: Methods Of Earth Leakage Protection
The test resistor to earth method is recommended with this type of protection as this test also proves the neutral to earth connection. See typical circuit, Page 16 - Drawings. ELDB006 Rev8 ELD V2 (2002) Earth Leakage Protection Relay User Manual Page 8... -
Page 10: Earth Leakage Toroids
Select the smallest internal diameter toroid, which will allow the cables to fit through. Avoid very large toroids (200mm) or toroids with square apertures. Only use approved toroids specified by Ampcontrol as these have been designed to minimise the problem. 4.4.2 Toroid Installation Guidelines Keep cables as close to the centre of the toroid as possible. -
