The microcomputer relay protection tester is a new generation of relay protection testing device developed by the current new electronic technology. It can independently complete the testing and debugging of devices and components in professional fields such as relay protection, excitation, and measurement. It is widely used in electric power, research, production and electrical test sites in railway, petrochemical, metallurgy and ore industries.

The output part is controlled by DSP, with fast calculation speed, strong real-time digital signal processing ability, wide transmission frequency, and high-resolution D/A conversion control. The output waveform has high precision, low distortion and good linearity. Adopting a large number of advanced technology and precision components and materials, and carrying out a professional structural design, the device is small in size, light in weight, full-featured, easy to carry, and it can work after booting, and the flow test is very convenient.
