Acrel Horizontal installation application for PT supervision/line/feeder/transformer AM2SE-H protection relay

Product Features

Product Introduction
AM series microcomputer protection measurement and control device (hereinafter referred to as the device) integrates protection, measurement and control. It is suitable for user terminal substations (stations) with voltage levels of 35kV and below, and can realize protection and measurement and control of user substations. The application fields cover electric power, water conservancy, transportation, petroleum, chemical industry, coal, metallurgy and other industries. The device adopts advanced, mature and reliable protection principles and algorithms, with strong anti-interference performance, high reliability, flexible protection implementation methods, and redundant communication design. The device has an independent high-precision current measurement circuit, multi-channel switching value acquisition and relay output. It can be used with the substation comprehensive automation system or the power plant electrical automation system to realize an unattended end-user substation power distribution automation system. The device can be installed centrally in a panel or directly installed on the switch cabinet for decentralized control.
