Protection relays and systems play an important role in electrical systems and are considered the cornerstone of smart grids for providing protection from electrical faults and ensuring the secure operation of the entire power system. One of the most important types of protection relays are WOVT3-208, which provide an overvoltage protection for power systems. This type of relays detects the overvoltage and provides a tripping command when the overvoltage has exceeded a certain level.

In order to understand the working principle of WOVT3-208, it is necessary to understand what overvoltage is and how it can affect an electrical system. Overvoltage is an electrical phenomenon caused by a voltage that exceeds the rated voltage of a device, such as a power supply. It is caused by lightning strikes, switching operations, power system faults, etc. and can destroy power equipment such as motors and generators if not detected and blocked in time.

The WOVT3-208 relays work by detecting the overvoltage and providing a tripping command when the overvoltage has exceeded a certain level. The relays incorporate an integrated circuit in the form of a rectifier, a transformer, a voltage level detector and a relay. The rectifier converts the incoming overvoltage into a high-frequency alternating current, which then passes through the transformer. The transformer is responsible for reducing the voltage levels. The transformer is followed by the voltage level detector, which is responsible for detecting whether the voltage is above a certain threshold or not. Based on the results of the voltage level detector, the relay will generate a tripping signal when the overvoltage exceeds the specified threshold.

The application field of WOVT3-208 can be divided into two parts: one is the Voltage Limiting System (VLS) and the other is the High-impedance Fault Detection (HFD). The VLS is used in protective systems to detect and limit high voltage in the power system. It is mainly used for the protection of power systems, generators and motors. The HFD system is mainly used for locating and isolating faults that may occur in the power system.

The WOVT3-208 is suitable for a wide variety of power protection applications such as industrial plants, commercial buildings and residential buildings. It provides a cost effective solution for providing a reliable overvoltage protection system. Additionally, the WOVT3-208 is designed to provide reliable performance over a wide range of operating conditions, such as temperature, load and supply voltage variations.

In conclusion, the WOVT3-208 relays are a reliable and cost effective solution for providing protection from overvoltage. They are used in power system protection applications such as Voltage Limiting Systems and High-impedance Fault Detection. They are designed to provide reliable performance over a wide range of operating conditions.
