Product Details

KPM83MD integrated electrical digital motor differential protection relay

Product Description

KPM83 series microcomputer comprehensive protection and measurement control devices is based on high-performance DSP processor and embedded real-time operating system, it is a protection and monitoring devices that integrated protection, monitoring and control, communications.

It is suitable for substations, power plants, industrial and mining enterprises, construction and other fields with voltage levels up to 35KV. It has such functions as protection, telemetry, remote mains, remote adjustment and remote control to achieve full control and management of it. , we can provide line protection and monitoring and control, transformer protection and control, motor protection and control, PT protection and control, capacitor protection and control, spare power source automatic throw-in device coupler protection and other product types.

KPM83MD integrated electrical digital motor differential protection relay is mainly used for comprehensive protection, control and measurement of transformers with voltage levels of 35KV and below.
