Certainly, I'm for The ” IT Earthing System “, especially in some places like :

– Hospitals ” Operation Rooms ” as we can't accept the tripping of electricity once an earth fault occurs.

– In the areas where the explosion's risk is high.

– In some applications where the continuity of service is very important.


By the way, the fault's location management is not easy, but if we install at the beginning the necessary products of ” IMD ” it will be more easier, because if we have many outputs after the Isolation Transformer, we can use the ” IMD ” equipments that's composed of ” one Injection equipment ” and ” Detectors equipments with Torroids ” where the number of them is suitable for the outputs' number, so, this combination can detect and locate the output where the fault occurs.
