WebThe M-0388 Syncrocloser® Check Relay is used as a permissive relay for secure reclosing of a circuit breaker by verifying that voltage and phase angle conditions are within pre-set limits before allowing the breaker to close. It is a panel-mounted, direct mechanical replacement for G.E. IJS and SLJ, and Westinghouse CVE relays. WebSyncronisers. However, they are not regarded as protection relays, and so are discussed in this article for convenience. There are two types of synchronisers: Check synchronisers and. Auto-synchronisers. 1. The function of a check synchroniser. The function of a check synchroniser is to determine if two voltages are in synchronism, or nearly so ...
