Partial Discharge Measuring System of Mold Transformer

In order to development of diagnosis system for mold transformer, partial discharge measurement technique is recommended the best effective method for the evaluation of insulation condition. However, this technique was not applied to mold transformer yet. The purpose of this paper is to describe the method of partial discharge measurement for mold transformer. As we reviewed on-line test technique, sensor, transducer of pulse signal processing, set-up of test circuit for loading back device and now testing.
