grounding mesh : which equiptment
grounding mesh : which equiptment
(OP)
hi,
at a 150 kV conventional substation (air insulation) that has LA, CVT, DS+E, DS, CB, CT, Tx, which one of these apparatus should be connected to grounding mesh?
and, which one should not be ?
thank you.

RE: grounding mesh : which equiptment
From your list of equipment, I would connect all that you have listed (except DS since I am not familiar with that).
If you have sensitive communications equipment, you may have to do something different.

LA = Lightning Arrester, CVT = Capacitive Voltage Tx, DS = Disconnecting Switch (E=Earthing), CB = Circuit Breaker, CT = Current Tx.
Next question is :
How about Lightning Arrester (or Surge Arrester?) ??
it is recommended to connect them with grounding mesh?
sorry, for repeating this question.

There is a controversial practice to ground sensitive electronic equipment to minimize "noise" problems. In the ANSI marketplace, is mandatory to ground all equipment.
There are a few exceptions such as series compensated cap bank steel platforms energized above ground potential. This is usually mounted on insulators and enclosed inside a fence to avoid direct contact to unauthorized personnel.
