LY-P200 microcomputer protection measurement and control device is applicable to the protection measurement and control of interval units of 10kV and below voltage levels. It has perfect protection, measurement, control and communication monitoring functions, provides a complete solution for the protection and control of substation, power plant, high and low voltage power distribution and plant power system, and effectively guarantees the safe and stable operation of high and low voltage power grids and plant power system. It can form an automatic control system with other protective devices and automatic equipment through communication interfaces. All devices can be installed in a centralized way by combine to panel assembly or locally in high and low voltage switchgear.
