Overcurrent And Earth Fault Relay

Overcurrent And Earth Fault Relay

•    The relay module is based on the Micom P122 industrial relay.
•    They can also use the relay support software and a suitable computer to program the relay module.
•    The relay module is then connected to the fault circuits so tests can be performed.
•    The lecturer or student sets up different fault circuits on the Protection and Relay Test Set.
•    They then use the keypad and display on the relay module to program it to the settings needed for the tests.
•    Most tests are performed using single relays.
•    Three-phase earth and overcurrent: three independent stages.
•    The first stage selectable from any of 12 IDMT curves.
•    The remaining stages having a direct time characteristic.
•    High impedance restricted earth fault.
•    Thermal overload protection.
•    Negative-phase sequence overcurrent: two independent stages.
•    Broken conductor detection.
•    Selectable blocking, Undercurrent.
•    Trend, fault and disturbance records.
•    Circuit monitoring.
