Description

According to the IEC and the relevant national standards, in power transformer production, the user acceptance and maintenance test process, the transformer ratio test is to do projects, it can effectively monitor the transformer products manufactured and used in the process of quality, prevent the transformer inter-turn short circuit, open circuit, connection error, voltage regulating switch internal fault or contact fault.

According to the user's requirements for the site use, we developed and produced the new type transformer ratio tester model HYG-II. It is a fully automatic tester that measures the transformation ratio of single-phase and three-phase transformers using modern electronic techniques and does not require any manual ‘null’ balancing. It makes the operation more convenient, complete functions, stable and reliable data, and test speed.

Advantages

Fully automatic: no manual balancing required

Test single phase and three phase transformers

Automatic measure transformer connection group

Automatic process transformation of the group

Automatic calculation of ratio error

Isolates test voltage automatically after test

Test results are saved automatically

Recall and print last the 30 test results

Prints results on the built-in printer
