Protection relays and systems are some of the most important components of any electrical system, ensuring the safe operation of equipment and personnel. The WOVT3-200 is one such device, equipped with features to provide protection from overvoltages and prevent costly downtime of electrical systems. This article outlines the application field of the WOVT3-200 and its working principle.

Application Field

The WOVT3-200 is designed for applications in motor feeders, industrial plants, electronic equipment rooms, and other similar power system configurations. This protection relay offers full protection for three-phase equipment against voltage sags, surges, and transients. It can be used as a standard differential relay for motor circuits or as a directionally sensitive detector with its high-level logic built-in for long-distance quick response.

Furthermore, the WOVT3-200 is also suitable for railroad, mining and hazardous area applications, due to its explosion-proof casing and integrated ground fault detection. Its wide temperature range, ranging from -30°C to +85°C further enables its use in extreme weather conditions. This protection relay device also offers a wide range of operating voltage from 24V to 600V AC/DC.

Working Principle

The WOVT3-200 works by detecting transient overvoltages or ground faults in a system, then quickly responding to shut off power to that system in order to prevent damage. To achieve this, the WOVT3-200 utilizes differential protection and fast-speed fault detection algorithms to detect any electrical transient between the relay and its connected equipment. This protects the system from any dangerous transients that could cause harm. Additionally, the device also works to monitor ground faults such as shorts caused by problems in the wiring system.

In addition, the WOVT3-200 utilizes a high-speed sampling mechanism and a state-of-the-art control logic to detect any weird behavior of the power system, further ensuring reliable protection against any transient disturbance. In order to do this, the device takes samples of system resistances and other parameters every 1.5KHz, then compare it with its reference sample to detect any discrepancies and subsequent transient activity. Finally, if a transient is detected, the device immediately initiates a quick-cut off procedure to shut off power, preventing further damage.

All in all, the WOVT3-200 offers reliable and energy-efficient protection against a wide range of overvoltages or transients that may occur in motor feeders, industrial plants, and hazardous areas. Its wide range of operating voltages, extensive protection features, and highly responsive logic, make it a reliable device for any application.
