(OP)
There is an installation that has my concern. A 34.5kV O/H line extension, dip with fused c/o to a 34.5kV to 4.8kV (1500KVA) dist. transformer X0 grounded to rudimentary ground ring. 3-wires up to another fused c/o and then more O/H secondary distribution line to multiple facilities. No Switch gear. No Ground fault relay. Poor ground conductivity in desert area. This bothers me but can not pin point NESC or NEC code violation. (this was a DB contract that went bad, contractor cut off payment from DOR A/E firm). Contractor running open loop. Is there a code issue, or ANSI (USofA) that is of issue here?






RE: GFP concern
If it is owned by an electric utility, they can basically do whatever they want. Separate ground fault protection is not required and is often not provided when only fuses are used. If you had a ground fault relay, what would you trip?
Lack of ground fault protection, in and of itself, is probably not a violation of any US codes.
