This paper introduces the item and requirements of the relay relationship checking. The main purpose of the transformer test is to determine transformer in the transport, the installation process and the operation of injury or whether the changes and the validation of transformers with the relational standards and technical conditions. This paper introduces the theory, methods and attention to the matter of the following test: the winding insulation resistance measurement; the winding with bushing dielectric loss factor tgδ measurement; the winding with bushing together DC resistance measurement; the OLTC switching sequence test; the transformer winding distortion test. The PD test of the current transformer can check local insulation defects and hidden fault. This paper describes the basic principles and operation of the current transformer partial discharge test using the FM-series resonant high voltage test equipment.
