LCD 3 Phase Voltage Monitoring Relay , JVR1000 Time Delay Undervoltage Relay
The three-phase power supply monitor is a device that provides relay protection for the three-phase motor input power supply voltage is too high, voltage is too low, phase failure, reverse phase, three-phase voltage imbalance. The protector can timely break the contacts of the switch electrical appliances, disconnect the three-phase power supply of the motor, and quickly and reliably protect the motor.
1 . Reverse phase: The phase sequence of the power input to the protected device is incorrect.
2 . Overvoltage: The operating voltage of the protected equipment is higher than the set value.
3 . Undervoltage: The operating voltage of the protected equipment is lower than the set value.
4 . Static phase loss: refers to the phase failure of any phase when the protected device is in the non-operating state.
5 . Dynamic phase loss: refers to the phase failure of any phase when the protected device is in the running state.
6 . Three-phase voltage imbalance: refers to a kind of voltage imbalance protection that affects the safe operation of the equipment due to the unbalance of the three-phase voltage.
1. Its protection function is not affected by the size of the line or load current, inrush current, unbalanced current, and load properties.
2. Ability to perform full-performance, climate-wide long-term work to ensure normal and stable operation of appliances and motors.
3. There is no requirement for motor wiring when used for motor protection.
