Microcomputer Protection Device,AM3SE
Microcomputer Protection Device,AM3SE
The AM3SE series microcomputer protection device integrates protection ，control and is suitable for user terminal substations (stations) with a voltage level of 35kV and below .Can realize the protection and control of user substations. The application fields cover electric power, water conservancy, transportation, petroleum, chemical industry, coal, metallurgy and other industries.
The protection device adopts advanced, mature , reliable protection principles and algorithms.With strong anti-interference performance, high reliability, flexible protection implementation mode, and redundant design for communication. The device can cooperate with the Acrel-2000Z power monitoring system to provide guarantee for the reliable operation of the user's substation power distribution automation system.
