The Synchro-check (paralleling) protector trip relay compares the voltage, frequency and phase angle of two supplies and operates a relay according to the state of synchronisation of the supplies. If the two supplies are not synchronised, the relay operates to provide a control output. The relay output can be used for alarm or control purposes. The unit also provides a dead bus function. If the bus supply fails, the relay operates and the output can be used to switch in an emergency generator.
Basic Parameters
- Available with three voltage ranges
- Adjustable nominal voltage range
- Adjustable synch tolerance
- Dead bus function on/off switch
- Power on LED (green)
