This system protects
industrial electrical equipment such as motors, transformers and
feeders, against the damage caused by low magnitude ground currents.
GFR-2 works effectively on both high and low resistance grounded
distribution systems. The package we provide consists of: Ground
Fault Protection Relay (GFR-2) Zero Sequence Current Transformer
the ground fault occurs in the system, the Sensor immediately sends
a signal to trip the GFR-2 relay. Skymatic Controls will provide
DPDT output contacts that operate breakers, annunciators and a wide
variety of other devices. GFR-2 is compatible with Skymatic Controls
sensors, or any other third party sensors, approved by Skymatic.
The GFR-2 is housed in a standard track mount DIN enclosure. CSA
approved, the GFR-2 relay has an excellent reliability record and
it has been installed in locations around the world. GFR-2 also
passed the Environmental and Seismic tests for Ontario Hydro Nuclear
Power Generating Stations.
