Description
The PGR-4300 Generator Ground-Fault Relay provides a simple
method for alarming a ground-fault condition on generators
without the need for current transformers (CTs). This greatly
simplifies the installation, and eliminates risks associated
with 3-pole and 4-pole transfer switches. This relay also
monitors the neutral-to-ground path for continuity.
Application
The PGR-4300 overcomes the complex CT configuration
required for 3- or 4-pole transfer switch operations. Detecting
ground-faults when a generator operates in conjunction
with a 3-pole automatic transfer switch is very difficult. The
PGR-4300 is ideal for any gen-set or application where there
is not sufficient space to install CTs.
