Medium Voltage Protection Relay
AM5SE Series Medium Voltage Protection Relay
OVERVIEW
The AM5SE series Medium Voltage relay integrates protection, control, measurement, communication and monitoring functions. It is rich in resources, well-configured, easy to maintain and has stable performance. It is suitable for the protection and control of power systems with voltage levels of 35kV and below, and realizes the protection of incoming lines, main transformers, distribution transformers, motors, capacitors, busbars, PTs, etc. The application areas cover power, water conservancy, transportation, petroleum, chemical industry, coal, metallurgy and other industries.
The device hardware design adopts reliability configuration, and the software is equipped with a special protection algorithm. It has strong anti-interference performance, high reliability, and flexible protection implementation methods. It can be used in conjunction with power monitoring system to provide protection for the safe and reliable operation of the power system.
