The basic function of the transformer relay protection tester is to protect the safety of the transformer. When the transformer has internal faults, it can be convenient and reliable to act on the switch tripping, removing the fault points, ensuring the safe operation of the power system, and protecting the transformer from damage. Today The editor will give you a detailed introduction to some aspects of the relay protection tester.


     The equipment standard of the microcomputer relay protection tester is basically the same as the conventional protection equipment, but due to the characteristics of the microcomputer protection software, usually the microcomputer protection equipment is relatively complete and sensitive. The microcomputer relay protection tester is similar to the line microcomputer protection in the protection hardware. , Due to the special requirements for protection, the software has outstanding characteristics in use.

      The differential protection of the microcomputer relay protection tester allows all current transformers to use Y-shaped wiring for the second time, and the current phase and amplitude compensation coefficient are automatically completed by the software, which makes the operation protection very convenient. The new type of transformer microcomputer protection is selected. The inspection sensitivity of the small current inside the transformer is much higher. The backup protection button equipment of the transformer also improves the normal use of the protection operation, and further plays the role of protecting the instrument.
