IDMT Overcurrent Earth Fault Relay
- 16 Bit RISC, state of art, microcontroller based System.
- Fundamental measurement of all measured parameters with 1% accuracy of measured value (Not full scale)
- Backlit LCD Display for easy reading and parameter settings. No need to consult the manual while programming the unit. All system parameters are user programmable
- All the inputs such as AC voltage and auxiliary voltage are completely isolated
- Fast Fourier Transformation to extract fundamental components of current and voltage to avoid spurious tripping
- Housed in 92X92mm Din Standard housing.
- Three Phase Over current Protection (COP-IE, COP-I)
- Three Phase Short Circuit Protection (COP-IE, COP-I)
- Earth Fault Protection (COP-IE, COP-E)
- High set earth fault protection (COP-IE, COP-E)
Display and Measurement
Display of R,Y,B Phase Current, Display of neutral / earth current
- Wide range SMPS auxiliary supply (supply range from 50 to 300 VAC/DC Or 8-35 VDC)
