Protection Relays & Systems are an important part of the power grid infrastructure and are used to detect and respond to power disturbances, monitor equipment performance, maintain consistent electrical power delivery and facilitate continuous operation of the power system. The WOV-3-440 protection relay is a type of multi-functional, three-phase overvoltage protection relay. It provides the necessary protection for voltage disturbances, phase-to-ground, point-to-ground, phase-to-phase, ground-to-ground, locking and tripping switches, etc.

The WOV-3-440 is a cost-effective solution to overvoltage protection as it is capable of monitoring voltage fluctuations in both normal and high voltage circuits. The relay also provides a backup power supply system for the operation of other protection relays in the event of an overvoltage surge or power failure. Additionally, the unit provides a visual LED alert and audible alarm when overvoltage conditions are detected.

The WOV-3-440 protection relay is primarily used in distribution systems to detect and respond to voltage disturbances in power systems. It has been designed as a self-contained unit, able to detect overvoltage, undervoltage and phase failure in three-phase systems. It also includes a locking and tripping ability to allow remote control of the power system. Additionally, the WOV-3-440 can monitor the performance of circuit breakers and other protective devices.

The working principle of WOV-3-440 protection relay is based on the detection of overvoltage conditions that exceed pre-specified set points. In the event that the overvoltage exceeds the preset set points, the protection relay trips the breaker to disconnect the load from the system. The WOV-3-440 can detect varying levels of overvoltage, allowing it to respond to both low and high voltage surges.

In addition to overvoltage protection the WOV-3-440 protection relay also provides the capability for monitoring of undervoltage conditions. The relay monitors the voltage level in each phase of a three-phase system, and if the monitored voltage level is below the pre-specified set point, the relay trips the breaker to disconnect the load.

The WOV-3-440 protection relay also has the ability to monitor phase failure. This feature allows the user to detect abnormalities in any of the phases of the three-phase system. The protection relay trips the breaker when phase failure is detected, and also provides a visual indication and audible alarm to alert the user to the abnormality.

The WOV-3-440 also has a locking and tripping feature that allows for remote control of the breaker. This feature allows the user to initiate a system event to manually trip the breaker in the event of an emergency or power outage. This feature can also be used to manually lock the breaker in the open position, preventing it from tripping casually.

The WOV-3-440 protection relay is a reliable and cost-effective solution for protecting electrical systems from overvoltage, undervoltage, and phase failure conditions. The WOV-3-440 has been designed with a robust set of features that allow it to provide reliable protection under various conditions. Additionally, the ability to remotely control the breaker allows for safe and effective management of the power system.
