An overview,

According to the relevant provisions of IEC and the state, transformer semi-finished products and finished products in the process of transformer production as well as newly installed and repaired transformers shall be tested for transformer ratio before being put into operation. In the "electric power equipment handover and prevention through the test specification" also requires that the transformer in operation is regularly measured. Transformer ratio test, can check the winding of the transformer, tap switch status, determine whether the transformer coil short circuit, connection error, inter-turn short circuit and other defects, so as to ensure the use of equipment.

The transformer ratio tester developed and produced by the company uses 32-bit ARM kernel as the processing core to control the whole machine. The measurement of single - phase or three - phase transformer ratio is completed at one time. All the operation of the instrument is displayed in Chinese menu, which is simple and intuitive. The test results are accurate and reliable, and can be stored and printed. Strong anti-interference ability. It can meet the needs of all kinds of large and small transformer ratio testing.
