The use of microcomputer relay protection tester

In the operation of the power system, the microcomputer relay protection tester is one of the essential test equipment. It can quickly and effectively detect the factors of power system operation failure, and provides an important guarantee for the safe and reliable operation of the power system.

Microcomputer relay protection tester is usually divided into single-phase microcomputer relay protection tester, three-phase microcomputer relay protection tester and six-phase microcomputer relay protection tester.

The main application of the three-phase and six-phase microcomputer relay protection tester in the power system is shown in the figure above.
