 Secure
reclosing of a circuit breaker
The M-0390 SyncrocloserŽ Check Plus 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. The M-0390 uses phase angle/slip frequency
to verify synchronism to provide rapid restoration with the smallest possible
angle settings. It is a panel-mounted, direct upgrade for G.E. IJS and
SLJ, and Westinghouse CVE relays.
- Panel mounted G.E. IJS and SLJ or Westinghouse CVE replacement.
- Accurate, independent phase, time, voltage and delta F functions
- Transducer and status outputs are standard features
- Modular construction allows cards to be removed while unit is installed
- Dead line/dead bus close capability is standard
- Does not require a separate power source
- Complete test and checkout from front panel
- 20A output relay contacts open 0.9A inductive as 125V dc
- Temperature range of -40° to +80° C
