transformer turns ratio tester/Automatic turns ratio TTR tester/transformer ratio group tester
Product introduction
According to IEC and relevant national standards, in the process of power transformer production, user handover and maintenance test, transformer ratio test is a common project, which can effectively supervise the quality of transformer products in the factory and use process, prevent transformer turn short circuit, open circuit, connection error, voltage regulator internal fault or contact fault. The function is complete, the data is stable and reliable, and the test speed is greatly improved. It can meet the needs of various transformer ratio testing.
Using the variable ratio group tester to measure the transformer's variable ratio, the operation process is complicated, the measuring range is narrow, and it has not adapted to the fast pace and high efficiency requirements of modern measurement. To this end, our company adopts modern electronic technology to develop a new generation of fully automatic variable ratio group tester. It is small in size, light in weight, high in precision and good in stability. It uses large screen Chinese character display, menu operation, friendly interface. The variable ratio group can be measured in one time.
