The spau 140 c synchronization relay can be used for both synchronization and voltage verification.
The synchronization check function is used when two separate networks or two electrically connected parts of a network need to be connected together.
The voltage check function is used when it is necessary to connect the disconnected bus/line to the current drive part of the network.
Synchronization verification allows the circuit breaker to close automatically only if the voltage on both sides of the circuit breaker meets the specified conditions of amplitude, phase and frequency difference
