Review on Partial Discharge Detection Techniques Related to High Voltage Power Equipment Using Different Sensors
When operating an equipment or a power system at high voltage , problems associated with partial discharge (PD) can be tracked down to electromagnetic emission, acoustic emission or chemical reactions such as the formation of ozone and nitrous oxide gases. High Voltage equipment and High Voltage...

| Summary: | When operating an equipment or a power system at high voltage , problems associated with partial
discharge (PD) can be tracked down to electromagnetic emission, acoustic emission or chemical
reactions such as the formation of ozone and nitrous oxide gases. High Voltage equipment and High
Voltage installation owners have come to terms with the need for conditions monitoring process of PD
in equipment such as power transformers, gas insulated substations (GIS) and cable installations. This
paper reviews the available PD detection methods (involving high voltage equipment) such as electrical
detection, chemical detection, acoustic detection and optical detection. Advantages and disadvantages
of each method have been explored and compared. The review suggests that optical detection
techniques provide many advantages from the consideration of accuracy and suitability for the
applications when compared to other techniques. |
