The microcomputer relay protection tester can manually or automatically test various types of voltage, current, frequency, power, impedance, harmonics, differential, synchronous relays, etc. It can simulate various types of faults for distance and zero sequence protection device setting verification and protection device group testing. It can automatically scan the differential protection ratio braking curve of microcomputer and digital transformers and generator transformer groups, and has GPS triggering function.
The relay protection tester mainly conducts preventive tests around relays, microcomputer protection, and other protective devices. The recommended modules for relay testing include: DC test, AC/DC test, AC test, differential test, differential harmonic test, power impedance, power direction and impedance test, and synchronous test; The microcomputer protection test mainly involves line protection, generator-transformer unit protection related tests, as well as automatic synchronization devices, backup automatic switching devices, and busbar differential protection related tests!
Microcomputer relay protection is widely used in various fields such as line protection, main transformer differential protection, excitation control, etc. Integrated automation of substations has become mainstream. It is an important testing tool to ensure the safe and reliable operation of the power system. With the rapid development of computer technology, microelectronics technology, and power electronics technology, the continuous introduction of new high-performance relay protection testing devices is an inevitable trend of technological progress.
