Partial discharge detector (also called partial discharge detection system) is a new type of instrument developed and produced. The partial discharge detector has high sensitivity and a wide test range. More importantly, it is easy to operate, so it is favored. So how to ensure the safety of PD detectors?

First of all, whether it is the operation of the partial discharge detector or the regular maintenance, it must be a competent professional. Others who do not know the partial discharge detector must not come into contact with the instrument. This is not only for the service life of the instrument, but also to ensure the personal safety of everyone.

Secondly, the voltage at the test point of the detector is as high as tens of thousands of volts, so relevant testers must strictly observe all safety precautions. Make sure that there are clear warning signs in the test area so that anyone on the scene knows where the high-voltage area is. During the test, no one is allowed to enter the high-voltage area. Before using the partial discharge detector to test, the operator should master the test method, test procedure and test purpose, and keep these in mind, which is very important for the test.

The test part of the partial discharge detector must be kept clean and tidy, and other items not related to the test must not be stored. Especially in high-pressure areas, there should be no metal fragments on the ground.

The surface of the test object, step-up transformer and coupling capacitor should be kept dry and clean. If there is moisture or dirt on the surface, it is easy to cause partial discharge and cause abnormal measurement.

To make the partial discharge detector play a greater role in the experiment, and make the entire measurement process more smooth, the operator must firmly grasp the above points in order to ensure the safety of using the partial discharge detector, and it can be extended to a certain extent. Its service life.
