Synchro-check Relay SPAU 140 C

Outdated product since 2012, replaced by REU615

The numerical synchro-check relay type SPAU 140 C is a voltage measuring relay designed to be used when two power systems are to be connected together.

The synchro-check relay SPAU 140 C can be used for both synchro-check functions and voltage-check functions. The synchro-check function is used when two separate networks or two electrically interconnected network sections are to be connected together. The voltage-check function is used when a disconnected bus/line is to be connected to an energized section of a network. The synchro-check function allows circuit breaker closing only if the voltages on both sides of the circuit breaker fulfill the preset conditions as to magnitude, phase and frequency difference.
