The synchro check relay spau 140 c can be used for both synchro check functions and voltage check functions.
Sync check relay.
Today these are digital microprocess.
The synchro check function is used when two separate networks or two electrically.
We would like to show you a description here but the site won t allow us.
Connecting two electrical systems that are not closely matched can cause expensive damage and disturbance to the electrical.
Synchrocheck relays ensures that bus and line side voltages are within programmed differentials of voltage magnitude phase angle frequency and phase rotation is the same.
Check synchronous relay setting.
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.
It means we can do still synchronization with the 1 5 voltage or frequency mismatch.
Sync check relay synchronism check relay are relays that allow unattended synchronization of a machine with a system.
The volt free relay contacts change state when the voltage level phase relationship and frequency are within the selected synchronising limits.
I have used the check synchronous relay with the setting of 1 5 mismatch.
