A Protection Relay is an electromechanical or solid-state device that provides an automatic means of protecting electrical power systems from damage due to excessive current or voltage. The WUV-125DC is a protection relay specifically designed for medium voltage applications. This article will discuss the application field and working principle of the WUV-125DC protection relay.

The WUV-125DC has been designed to meet the demanding requirements of high, medium, and low voltage applications. It is commonly used in critical application fields such as data centers, hospitals, and mission critical systems. The WUV-125DC provides advanced protection and supervision to the circuit breaker and enables secure electrical distribution systems to be used with greater reliability. It can be used in applications where an increased level of protection is required, such as motor protection, circuit breaker protection, transformer protection, busbar protection, and generator protection.

The key advantage of WUV-125DC is its flexibility and ease of configuration. All the parameters of this relay can be adjusted quickly without any external tools. The parameters can be configured via the front keypad or a personal computer connected to the RS232 port. It can also be connected to a remote server or control system.

The WUV-125DC relay operates using a three-phase protection scheme. It monitors the capacitive and inductive current, as well as the phase voltages of a three-phase system. It also monitors the neutral current during single-phase faults. When an overcurrent is detected, the relay trips the breaker. It also monitors the balance of the three-phase system and will trip when an unbalanced current is detected. The WUV-125DC relay is also equipped with temperature monitoring and will automatically trip the breaker when the temperature rises above a preset level.

The WUV-125DC relay also supports other advanced features such as overvoltage and undervoltage protection, earth fault protection, reverse power protection, and load shedding. It also has an integrated timer that can be used to control and protect the generator or motor. In addition, the WUV-125DC relay is also capable of automatically restoring the power supply in case of a blackout.

In conclusion, the WUV-125DC is an advanced protection relay specifically designed for application in medium voltage systems. It provides a comprehensive range of protection features for the circuit breaker and allows for secure and reliable electrical distribution. Its flexibility and ease of configuration make it ideal for a variety of critical applications.
