Protection Relays & Systems: SE-330HV-22-00

The SE-330HV-22-00 is an intelligent digital over-voltage/abnormal voltage protection relay, designed by the industrial automation systems company, SE Electric. This device is designed to sense and monitor the voltage between two phases, and in the event of abnormal voltage or a voltage surge, it will activate the surge protective device (SPD) in order to protect connected equipment from damage.

Application Field

The SE-330HV-22-00 is most commonly used in industrial environments to provide protection against voltage surges or abnormal voltage, such as might be caused by lightning strikes or brownouts in the power grid. It has wide-ranging applications and can be used in any environment where the protection of connected equipment is important. It can be used in substations, power plants, manufacturing plants, and other industrial and commercial facilities. Additionally, it can be used in residential and light commercial settings to provide additional protection to sensitive equipment.

Working Principle

The SE-330HV-22-00 operates on a self-powered, two-stage sensing principle. In the first stage, the relay will monitor the voltage between two phases and detect any abnormalities in the voltage. If any abnormalities are detected, it will enter into the second stage and compare the voltage against pre-set limits. If the voltage exceeds the limits, the relay will activate a protective device, such as an SPD. The SPD will then provide protection to connected equipment against damage.The relay also features a built-in self-test feature that will monitor the relay for any malfunctioning components and alert the user to any potential problems. This feature helps to ensure reliability and reduce downtime due to malfunctions.

Benefits

The SE-330HV-22-00 offers a number of benefits for users. The two-stage sensing mechanism helps to ensure reliability and reduce downtime due to malfunctioning. The built-in self-test feature is also a great benefit, as it can help to diagnose any potential problems quickly and help to reduce downtime. Additionally, the device is compatible with a wide range of SPDs, making it a flexible solution that can be tailored to the needs of any particular application.Overall, the SE-330HV-22-00 is an intelligent and reliable way to provide over-voltage/abnormal voltage protection against power outages and surges. Its two-stage sensing mechanism and built-in self-test feature make it a reliable device for protecting your connected equipment. Additionally, its compatibility with a wide range of SPDs makes it a flexible solution that can be tailored to meet the needs of any particular application.
