Protection Relays & Systems are a critical part of any power system and the WOV-1-480 is no different. This type of protective relay is specially designed to provide protection for motors and other electrical equipment. The WOV-1-480 includes several elements that allow it to recognize and respond quickly to the changing conditions of a power system, thus ensuring robust motor and system protection.

The application field of the WOV-1-480 covers generators, motors, transformers, electrical drives, and other power system components. It provides motor protection, power factor correction, generator protection, and transformer protection. It also features an EMFL (Earth Magneto Flux Limiter) with Metering and Fault Alarm function. The WOV-1-480 also offers isolation and synchronization of power systems.

The WOV-1-480 utilizes a variety of standards, such as IEC, CE, ANSI, UL, and CAN CSA, to ensure high quality protective relay performance. The product can also be adapted to other standards, like CCC, GOST, and CUL, allowing for a larger market coverage. It is also approved by Underwriters Laboratories.

The WOV-1-480 is operated using a graphical user interface (GUI) with an embedded watchdog timer for improved reliability. Its intuitive and convenient interactive features allow for easy operation. It offers 10 different functions, ranging from setting the time delay, amp pick-up, and power factor to the alarm setting, metering, and fault alarm.

The main working principle of the WOV-1-480 is to detect and monitor rapidly changing conditions on a power system. Utilizing the 3-phase current inputs, the WOV-1-480 will analyze the system, recognize, and respond to changes within a range of 0.01 to 5000Hz. When a disturbance, like a short circuit, is detected, the relay will instantly trip and disconnect the supply.

The WOV-1-480 also provides important information related to the system, such as over-current monitoring, voltage sorting, temperature monitoring, and more. The internal algorithm for detecting and responding to faults is very reliable and can be adjusted as needed. This provides the user with assured protection for motors and other system components.

The WOV-1-480 also has built-in monitoring functions for ground fault and phase reversal. For cases of system voltage reversal, the relay will open the circuit breaker connected to it, preventing further damage. Also, if the system voltage exceeds a certain limit, the relay will automatically trip the breaker.

The WOV-1-480 protective relay provides accurate protection even in highly dynamic or fluctuating power systems. It can also be configured to adjust its own performance in response to changing system conditions. This allows it to respond quickly and effectively to events, while helping to improve the safety and efficiency of the power system.
