Overcurrent and Earth Fault Relay Setting
Setting calculation is separated for overcurrent and eart fault relay. For both settings, there are few following input parameters:
- Name of Feeder
- Load Current: (IL) in Amps
- Min Fault Current (Line-Line) in Amps
- Max Fault Current (Line-Line) in Amps
- Relay Type
- Relay Code
- Relay No
- CT Primary Current (in Amps)
- CT Secondary Current (in Amps)
- Relay Error (%)
- CT Error (%)
- Over shoot (in seconds)
- C.B Interrupting Time (in seconds)
