GRT100 has two model series which differ according to the number of three-phase current inputs
for differential protection as follows:
Relay Type and Model
Relay Type:
- Type GRT100; Numerical transformer protection relay
Relay Model:
- Model 100 series; 2 three-phase current inputs, applied to two-winding transformers
• Model 101; 16 binary inputs, 13 binary outputs, 5 binary outputs for tripping
• Model 102; 16 binary inputs, 23 binary outputs, 5 binary outputs for tripping
- Model 200 series; 3 three-phase current inputs, applied to two- and three-winding transformers
• Model 201; 16 binary inputs, 13 binary outputs, 5 binary outputs for tripping
• Model 202; 16 binary inputs, 23 binary outputs, 5 binary outputs for tripping
• Model 203; 15 binary inputs (12-independent), 13 binary outputs, 3 binary outputs for tripping
• Model 204; 15 binary inputs (12-independent), 23 binary outputs, 3 binary outputs for tripping
Model 100 series have 2 three-phase current inputs and can be applied to two-winding
transformers. Model 200 series have 3 three-phase current inputs and can be applied to two- and
three-winding transformers.
