Certificate of Partial discharge testing(CPDT) (Level-C)
Course outline
This course introduces the type of partial discharge and use the partial discharge meter to evaluate insulation level, students have the following ability after the course.
1.Operate of the partial discharge metrical meter.
2.Has knowledge of PD principle and PD phenomenon about all the HV apparatus.
3.Identify the PD types of HV apparatus based on the measuring waveform and its frequency response.
4.Set up the infrastructure of smart substation
Course Description
The goal of this course is to give a systematic training to test engineers so that they are able to learn the PD testing skill in a short period. After qualification, the engineer have the professional knowledge about HV apparatus and its PD testing methods. With these abilities, they can operate PD detecting instruments to test HV apparatus and judge whether the insulation degrades or not based on the measuring data of the instruments. Therefore, the failure rate of HV apparatus can be decreased, which then results in the reduction of the economical and safety losses
