1.transformer oil dielectric loss meter  Description 

I.Introduction

In the preventive test of electrical equipment insulation, a periodic measurement for the parameter of insulation oil was required. The insulation oil dielectric dissipation factor and d.c. resistivity measurement is one of the main methods in a series of preventive tests. Bridge method mostly used for a long time, but this method is complex to operate, also the measurement accuracy will influence by many factors, and that may easily result in a large measurement error. Along with the electronic technology are highly improved, the power industry’s requirements in the measuring apparatus are continuing increase, including small volume, light weight, easy to operate, fast speed and high precision. Based on related foreign and domestic instrument, our company successfully developed HZJD series products, which is relatively advanced in our country at this present. Our instrument are design and manufacture basis on GB5654 and other relative standards, using computer control, simple to use, high accuracy and very efficient, dramatically reduced labor strength of testers.
