Protection Relays & Systems play an essential role in ensuring the safe and reliable distribution of electricity to homes and businesses. SE-330HV-21-01 is an overvoltage protection relay. It provides a fault detection system and can be used in many different application fields, including high voltage electricity grids, industrial applications, and municipal electricity systems. The product can be used to detect and protect against voltage transients, sustain high voltage levels, and generally improve system safety.

This protection relay has two parts: the monitoring circuit and the control circuit. The monitoring circuit is responsible for monitoring the voltage levels in the system and compares it with the preset relay parameters. The control circuit receives the signals from the monitoring circuit and sends the relevant protection commands to the control system. The relay output can also be used to drive motor, fans, and other devices.

The working principle of SE-330HV-21-01 is based on the principle of tracking a voltage transient. It uses a 7-step moderate scanning which bins the monitored voltage in various levels and then compares it to the preset parameters. If the voltage transient exceeds the preset limits, the relay activates the protection command. The detecting time of the relay is short — usually within 8 milliseconds — making it suitable for quick and effective protection.

SE-330HV-21-01 is often used in industrial and municipal electricity systems as protection against structural damages due to overvoltage. The relay prevents the system from experiencing a damaging event and stops the spread of any potential damages. It can also be used in high voltage electricity grids and substations to monitor voltage levels and prevent safety incidents. The product is suitable for environments with extreme temperature or with hazardous contents, such as explosive atmospheres and acidic conditions.

SE-330HV-21-01 is a reliable tool for protecting electricity grids and can provide peace of mind to those who use it. With accurate monitoring and quick response times, the protection relay helps to ensure that the electricity stays safe and secure, making it a valuable asset in any electric system.
