Protection relays and systems are used to protect industrial and power systems from hazardous conditions such as electric arc, fire, over-voltage, or over-current. The WOV-3-380 is an LV/MV protection relay designed specifically for indoor use. It functions as a control unit that automatically opens the circuit breaker in case of any fault in the system. The WOV-3-380 can detect over-voltage, over-current, and under-voltage conditions, as well as earth-fault and asymmetric current protection.

The WOV-3-380 is designed with a modular architecture, allowing the user to combine a variety of functions in one unit. It offers an adjustable current cutoff, adjustable voltage cutoff, and adjustable frequency cutoffs – all of which can be adjusted by the user. Additionally, the WOV-3-380 comes with an integrated two-wire search loop, allowing the user to remotely monitor the system.

The WOV-3-380 has a built-in Data Recording System which collects information related to faults and events that occur in the system. This data can then be analyzed and used to improve the system’s reliability and efficiency. Additionally, the WOV-3-380 has built-in reporting features which can be used to provide reports on system performance and faults.

The WOV-3-380 has wide application in various industrial and power systems. It is commonly used in industries such as power utilities, energy distribution, process plants, offshore platforms, and in the marine environment. In these industries, the WOV-3-380 is used to provide reliable low voltage/medium voltage protection from dangerous electrical faults. Some typical applications of the WOV-3-380 include overvoltage protection, under-voltage protection, over-current protection, earth-fault protection, and asymmetric current protection.

The WOV-3-380 works by detecting changes in the voltage and current in the system. It is capable of detecting both high and low values of voltage and current, and comparing them against predefined threshold values. When a value exceeds the preset value, the WOV-3-380 will send out an alarm signal to the system operator, indicating a possible fault. Depending on the type of fault detected, the system operator can then decide to either manually reset the system, or to automatically open the circuit breakers to prevent further damage.

In addition to its protection capabilities, the WOV-3-380 is also equipped with an integrated digital communication interface. This interface allows the WOV-3-380 to communicate with other systems in the same network, and with remote operators. This communication ensures that any faults and events are reported to system operators in a timely manner and allows for the automatic opening of circuit breakers in the case of dangerous conditions. This communication also allows the system to be remotely configured and monitored.

In short, the WOV-3-380 is a highly capable protection relay that is designed for use in industrial and power systems. It can detect overvoltage, under-voltage, over-current, and earth-fault conditions, as well as asymmetric current protection. Additionally, it is equipped with an integrated Data Recording System, reporting features, and digital communication interface. These features allow the system to be monitored and configured remotely, ensuring reliable protection against dangerous electrical faults.
