Acrel AM series medium voltage protection relays integrates protection, measurement and control. It is suitable for user terminal substations (stations) with voltage levels of 35kV and below, and can realize the protection and measurement and control of user substations. Applicable to electric power, water conservancy, transportation, petroleum, chemical, coal, metallurgy and other industries.

It integrates various functions such as protection, measurement, control, monitoring, communication, event recording, fault recording, and operation error prevention. It can cooperate with the operating system to complete the functions of substation control, protection, and anti-misoperation locking, and can also independently complete the complete set of protection and measurement monitoring functions for small and medium-scale unattended substations of 35kv and below or medium and low voltage sides. It can be installed in a decentralized way, or can be assembled in a centralized manner.
