LDR microcomputer protection device is a new generation of relay protection equipment developed by our company specifically for power plants, substations, distribution stations, etc. in the power system. It offers comprehensive protection for primary equipment such as overhead lines, cable lines, transformers, motors, and capacitors at voltage levels of 35kV and below.

This device consists of a single-chip microcomputer with high integration and a bus without chip, high-precision current and voltage transformers, high-insulation strength export intermediate relays, and reliable switching power supply modules. Its advantages include high integration, complete protection configuration, strong anti-interference ability, low power consumption, and resistance to harsh environments. It is particularly suitable for direct and decentralized installation on switch cabinets.
