TVR2000-1 Phase Failure Relay:over/under /Static phase/Phase sequence /Phase unbalance
Detailed introduction to TVR2000-1 Phase Failure Relays:
the protection functions of TVR series never be affected by current intensity of circuit or load, impulse current, unbalance current and load device.
Measure highest voltage value when over voltage.Measure lowest voltage value when under voltage. 5 LED indicators.
Over/under voltage protection is according to the average voltage and needs 8 seconds' confirmation.
Measure average value when over/under voltage. Instant protect action when phase loss or phase reversal. Alarm after 8 seconds continous fault. 5 LED indicators
