WOUF-12-60-T

Protection relays are an essential element in the power system, and are responsible for monitoring the vital parameters of the system and preventing catastrophic failures. One such protection relay is the WOUF-12-60-T, which is used to protect power systems from situations where there is an unbalance between incoming and outgoing currents. To understand how this protection relay works, a brief overview of its application field and working principle is necessary.

Application Field

The WOUF-12-60-T protection relay has a wide range of applications such as power plants, transmission networks, and high and low voltage industrial systems, where imbalances in current can occur due to disturbances or system faults. This relay monitors the system and reacts to maximise the system stability and prevent any catastrophic event.

Working Principle

The WOUF-12-60-T protection relay works by monitoring incoming and outgoing current, and when it detects a difference between the two, a signal is sent out to the overcurrent relay. The overcurrent relay will then trip the main circuit breaker, isolating the imbalance from the rest of the system and preventing more damage from occurring.

The WOUF-12-60-T provides detailed information about the system\'s current conditions, such as when a change in current is detected, or if it needs to be reset. It can also be configured to detect over-currents, under-currents, and even harmonic currents. The relay also provides information regarding the latency time between the fault being detected and the circuit being opened – this information is then used to adjust the time-delay settings accordingly.

The WOUF-12-60-T protection relay is a very reliable protection system that can quickly detect imbalances in current and react swiftly to prevent further damage to a system. It has a wide range of applications, and its configuration and sensitivity settings can be customised to suit any system environment.
