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

Sync check relay abb. Ansi solid state synchronism check relay type 25v solid state relay designed for distribution systems these relays are used to verify that the voltages on either side of a circuit breaker are synchronized and in the proper phase and magnitude relationaship to allow automatic closing. Energizing inputs terminals 13 14 16 17 19 20 13 15 16 18 19 21 rated voltage un 100 v 110 v continuous voltage withstand 2 0 un burden at rated voltage 0 5 va. 87 88 output relay b provides the permission signal for cb closing via stage 2 of the synchro check relay module. The synchro check relay spau 140 c can be used for both synchro check functions and voltage check functions.

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. Synchro check relay product guide spau 140 c 1mrs750421 mbg 5 technical data table 1. 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. 70 71 72 output relay d terminals 70 71 72 operates as the output relay of the self super. 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. Check synchroscope 96 lcsync introduction.

Abb type designation catalog description. 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.
