Blocking Pilot POTT schemes for GOAB switching
(OP)
For a 138KV fiber optic POTT scheme on network lines with a POTT instanteous O/C ground setting of about 300 amps, does your utility block the scheme during GOAB (group operated air break switching) on the lines?

The instantaneous elements are set above the pole disagreement level with some more sensitive elements set to trip on a time delay.
