Microcomputer-based protection is composed of components such as high integration, bus chip microcontroller, high-precision current and voltage transformer, high insulation strength outlet intermediate relay, and highly reliable switching power supply module. The microcomputer protection device is mainly used for power plants, substations, distribution stations, etc. with voltage levels of 110KV and below, and can also be used for the protection and measurement of voltage and current in some systems with voltage levels between 70V-220V
Periodic inspection period for microcomputer protection devices(1) Newly installed microcomputer protection devices shall undergo a comprehensive inspection once within one year, and thereafter, a full inspection shall be conducted every six years (the total inspection time for microcomputer line protection devices in 220kV and above power systems is generally 2-4 days)
Function of testing report:
