DBB-II Transformer Turn Ratio Tester

Product Introduction

In the semi-finished transformers and the finished the transformers production process, before the newly installed transformers being put into operation, and according to the preventive tests of the Ministry of Electric Power, the Turns and ratio of the transformers should be tested periodically. The traditional variable ratio electric bridge operating is cumbersome, and not intuitive for readings. It also needs to carry out the necessary conversion. The test results only for the information of one phase transformation ratio. DBB-II Transformer Ratio Tester overcomes the traditional variable Bridge Test shortcomings. A big screen used lattice liquid crystal monitor, with English menu suggested function. The operating is simple and intuitive. It can complete a three-phase variable ratio testing .Fast testing speed and high accuracy rate.
