Description
This following article presents the concept of a cheap universal capacitive sensor for partial discharge (PD) measurement. The authors checked the effectiveness of the device prototype on a MV air-insulated switchgear. For this purpose, a combination of a widely used Transient Earth Voltage (TEV) sensor and a detector with Junction Field-Effect Transistor (JFET) was used. The paper presents the results of PD measure- ments with TEV sensors depending on the phase of the supply voltage. The conducted experiment is the basis for developing the functionality of the sensor and further research.
