Background
Transformer substation, place of changing voltage. In order to transmit the electric energy generated by the power plant to a remote place, the voltage must be increased to become high voltage, and then the voltage is decreased as required near the user, and the voltage increasing and decreasing work is completed by a transformer substation. The main equipment of a substation are switches and transformers. The small transformer substations are called as transformer substations according to different sizes. The transformer substation is larger than the substation. The transformer substation refers to a step-down transformer substation with the voltage grade below 110 kV; the transformer substations comprise 'boosting and reducing' transformer substations of various voltage grades. A substation is an electrical facility in an electrical power system that transforms voltage, receives and distributes electrical energy, controls the flow of electrical power, and regulates voltage, and it connects the grids of the various levels of voltage through its transformers. With the continuous development of modern science and technology, the power system is also the basis of all intelligent devices, once the power system breaks down, the power system will cause the loss that is difficult to imagine, also bring a lot of inconveniences in all aspects.

At present, most of relay protection device testing work, especially static mode tests, still adopt the traditional method of using a relay protection tester to manually test, and have the defects of low testing efficiency, large influence of human factors and the like.
