why after termination of HT cable armoured earth connected
one end, why not connect other end.pls tell me correct
answer.

Answer Posted / ma khira

Practically The earthing resistance of two pits at different location cannot be same hence if you will connect cable Armour at both the end, close loop will be created and leakage current will flow which is harmful to the device.

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
