Grounding of PEN in a TN-C earthing system
Grounding of PEN in a TN-C earthing system
(OP)
Dear forumeers,
IEC Standards:
In a TN-C earthing system can the PEN conductor be grounded at the power center side in lieu of at the transformer side?
If yes, what are the pros and cons of the two options?
Can it be grounded both at transformer and at the power center ?
Thanks in advance.

RE: Grounding of PEN in a TN-C earthing system
If the neutral[PEN] is earthed in multiple points part of current will flow uncontrolled through the earth and the earthing [or neutral] current cannot be separately monitored.
