WUVT1-460

Protection relays and systems are essential components of the power system to guarantee the reliable operation of safety and power supply. WUVT1-460 is an over-current and voltage protection device designed for power distribution networks to protect against overload, over-voltage, under-voltage, short-circuit, and other similar faults. This paper will discuss the application field and working principle of WUVT1-460.

WUVT1-460 is compatible with various distribution systems like three-phase, single-phase, double pole, three-pole, and four-pole systems. It has two tripping circuit outputs that can be connected to either relays, fuses, circuit breakers, or other protective components. Therefore, if a fault occurs, these tripping circuits signal the main breaker to trip in order to prevent damage to downstream equipment. Additionally, WUVT1-460 also has an alarm output, which can be connected to alarm indicators such as sirens and lights. This alarm is used to alert operators of the fault status.

The input of WUVT1-460 is the current or voltage of the secondary circuit of the current transformer or voltage transformer. The input parameters of WUVT1-460 can be set via DIP switch or remotely by SCADA. WUVT1-460 provides adjustable parameters including trips delay time, tripping (closing) time, voltage and current trip set point, alarm set point, and alarm delay time. These parameters can be set as needed.

When the monitored current or voltage surpasses the set point, the over-current or over-voltage protection is triggered and the trip and alarm outputs will be activated. The WUVT1-460 utilizes a microprocessor-based relay which provides precise and reliable protection against overload, over-voltage, under-voltage, short-circuit, and other similar faults. It also offers an over-temperature protection feature, which will automatically disconnect the main breaker when the device’s temperature exceeds a set limit.

In conclusion, WUVT1-460 is a highly advanced over-current and voltage protection relay that can be used in power distribution networks for a variety of protection applications. It is compatible with various distribution systems and can be adjusted via DIP switch or remote SCADA. The device utilizes a microprocessor-based relay for precise and reliable protection against overload, over-voltage, under-voltage, short-circuit, and over-temperature conditions.
