The WOV-3-460 is a type of overvoltage protection relay, which is often used in many kinds of protection relays and systems. This article will discuss the application fields and working principles of WOV-3-460.

Application Field of WOV-3-460

The WOV-3-460 is designed to provide the user with a reliable and cost-effective protection against overvoltages. The device is usually used in high-voltage electrical systems, such as those found in power plants, industrial sites, and transmission networks. The WOV-3-460 is also suitable for many other applications, including surge protection for electronic equipment and high-speed data communication lines.

The WOV-3-460 is equipped with a set of components, including two contactors (one for energizing and one for stopping the relay), a voltage sensing coil, and a set of resistors. The working principle of the WOV-3-460 is quite simple: When the voltage exceeds the adjustable level, the voltage sensing coil will activate the contactors, interrupting the power supply.

Working Principle of WOV-3-460

The WOV-3-460 is a time-delay overvoltage protection relay with a voltage monitoring range of 85-610V AC. The device features a quick response time and adjustable trip settings through the voltage setting resistor. When the voltage exceeds the set levels, the relay will open and disconnect the power supply from the load.

The WOV-3-460 also features short-circuit protection, which can detect and protect the electrical system from any high-impedance faults. The device is equipped with both a high-sensitivity current sensing circuit and a current transformer, which provides a quick response time and precise current measurements. Once the fault is detected, the relay will open and cut off the power supply to the circuit.

The WOV-3-460 also offers a reset and testing function, which allows the user to test the relay and ensure it is working correctly. The device also has built-in diagnostics, which can detect any faults and indicate the exact causes.

Conclusion

The WOV-3-460 is a cost-effective and reliable overvoltage protection relay, which is often used in power plants, industrial sites, and transmission networks. The device features adjustable trip settings, short-circuit protection, reset and testing functions, and built-in diagnostics. It provides a reliable and accurate protection against overvoltages, and is thus an ideal choice for protection relays and systems.
