Product Introduction

Transformer ratio polarity tester. According to jjg313-94 current transformer for measurement and jjg313-93 voltage transformer for measurement, on-site ratio test must be conducted during transformer handover and after winding replacement.

The inspection method of the transformer's change ratio is the current method, which is easy to understand and feasible in principle. However, with the increase of system capacity, the primary current of the current transformer becomes larger and larger, up to tens of thousands of amperes.Site to hundreds of ampere current existing difficulties, thousands or tens of thousands of ampere ampere is almost impossible, and large volume, weight weighs several hundred kilograms or several tons, field use more difficult, such as the low current method, due to current transformer magnetic sensitivity, linearity, impedance, the influence of leakage reactance can make current transformer error jump, lost the meaning of change than check.

The transformer transformer ratio tester is small in volume, light in weight, wide in measuring range and easy to carry.The htct-200 transformer ratio polarity tester is developed by our company by summarizing the characteristics of transformers at home and abroad, applying the new research theories and results, and combining the requirements of field use.
