Operates on solidly grounded AC systems.
The PGR-4300 Generator Ground-Fault Relay provides
a simple method for detecting a ground-fault condition
on generators without the need for current transformers
(CTs). This greatly simplifies the installation. In addition,
it is compatible with both three- and four-pole transfer
switches. This relay also monitors the neutral-to-ground path
for continuity. The PGR-4300 is ideal for any generator or
application where there is not sufficient space to install CTs.
