Sync Check Relay Abb

Product scope type 25s synchronism check only type 25v synch check with dead bus dead line options.

Sync check relay abb.

Our range of two types of synchroscopes are microprocessor controlled. These relays allow closing when both bus and line voltages are approximately normal equal in phase and of approximately the same frequency. Synchro check relay product guide spau 140 c 1mrs750421 mbg 5 technical data table 1. Check synchroscope 96 lcsync introduction.

Rasc synchro check relay created date. 85 86 output relay c provides the permission signal for cb closing via stage 1 of the synchro check relay module. For this reason it is normal practice to have the sync check relay function provided in a different package than the automatic synchronizing relay to. 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.

Generator sync check relays should supervise both manual and automatic modes of operation to prevent generator damage from operator errors or from malfunctioning automatic synchronizing relays. Pentagon instruments are the oem of the 96 lsync 96 lcsync synchroscopes. Our led synchroscopes are designed to be used for manual synchronisation and the led s will optically indicate the electrical phase difference between two ac voltages. The synchro check relay spau 140 c can be used for both synchro check functions and voltage check functions.

87 88 output relay b provides the permission signal for cb closing via stage 2 of the synchro check relay module. Abb type designation catalog description.
