Reclosing on 27.6 kV
Reclosing on 27.6 kV
(OP)
Hi All,
I am programming a GE relay for a new feeder in a 27 kV station. feeder length is approx. 7 miles. Approx. 3 miles of feeder length is underground cable and rest is overhead line.
Is there a thumb rule that can advise for this feeder not to have reclosing because approx. 50% of feeder length is cable.
Any suggestions ?

In recent years, customers seem much less tolerant of reclosing operations - seeming almost to prefer a longer outage than the brief blips that create problems for all of their electronics.

From protection perspective possible do few options for shots, depend on the fault type, etc...
RE: Reclosing on 27.6 kV
It is a arguable point. For a feeder that is 99% underground and 1% overhead, I don't think very many would argue for reclosing. So obviously, there is a tipping point somewhere.

The difference between overload and short circuit lies in the nature of the fault, not in the value of the current.
