5A transformer ohmmeter Introduction

Transformer resistance test is the necessary test item for the delivery test, installation and transfer test of the semi-finished and finished products that in manufacturing. It is also the necessary test item for the electricity sector preventive test. It can effectively find and the manufacturing defects such as: selection and welding of the transformer coil; loosing, missing shares, break wire of the connecting parts. And it also can effectively find the hidden danger that after running. To meet the rapid measurement of the transformer winding resistance needs, our company used their technological advantage, developed this instrument. It adopted new power technology, which has s characteristics such as small volume, light weight, and large output current, etc. The whole unit is controlled by a monolithic processor which can complete automatic self-test, data processing and displaying. It also has automatic discharge and discharge instructions function. With high testing precision, easy to operate advantages, it can realize the rapid measurement of the transformer winding resistance.

5A transformer ohmmeter Characters
