Transformer Protection GRT 100

GRT100 is a numerical transformer protection relay, which can be applied for two-winding or three-winding power transformers,auto- transformers and generator- transformer units.

The main transformer differential protection is supported by restricted earth fault, back-up overcurrent, thermal overload, over-excitation and frequency protections.   In addition there are standard GR-series features such as metering, data recording and communications.
