M-0188A Syncrocloser® Check Relay Beckwithelectric Vietnam, M-0188A Syncrocloser® Rơ le kiểm tra Beckwithelectric Vietnam, Đại lý Beckwithelectric Vietnam
The M-0188A 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. Adjustable front panel controls are provided for upper and lower voltage limits, voltage difference (ΔV) limit, phase angle limit, time delay and dead line/bus limits. Analog outputs of phase angle, voltage and ΔV are provided for SCADA system interface. Phase angle, voltage and time delay dial settings are independent and do not vary with input conditions.
- Accurate, independent controls require no additional instrumentation for field setting.
- Voltage limit ranges and dead line/dead bus closing features are optional.
- Remote contacts to shift phase angle or time setpoints are standard.
- Transducer analog outputs are SCADA compatible.
