Directional/Non-Directional Overcurrent Relay

Directional/Non-Directional Overcurrent Relay

•    The relay is housed in a robust enclosure with carrying handle.
•    The module mounts on the desk area of the Protection and Relay Test Set, and connects to it using a multi-core cable and safety leads.
•    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.
•    They can also use the Micom S1 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.
•    Most tests are performed using single relays.
•    Three independent stages of directional/non-directional phase overcurrent.
•    The first stage may be set to any of 12 IDMT curves, the remaining two having a direct time characteristic.
•    Thermal overload protection.
•    Undercurrent.
•    Undervoltage.
•    Overvoltage.
•    Negative phase sequence overcurrent.
•    Directional/non-directional earth fault.
•    Selectable blocking.
•    Creating fault and disturbance records.
