Discover how AC and DC PD measurements are performed to reliably assess insulation condition.
Partial discharge (PD) measurement and analysis are highly effective for assessing the condition of electrical insulation.
Most PD measurements have been typically performed under AC voltage to detect potential failure-causing insulation defects.
However, the shift towards decentralizing energy supplies and the growing number of solar power generation stations, remote offshore wind farms, electric vehicle charging stations, and HVDC power transmission systems have dramatically increased the development of DC power grids. This in turn has intensified the need for measuring PD under DC voltage as well.
In this episode, OMICRON PD measurement and analysis experts Bogdan Gorgan and Ulrike Broniecki discuss the importance of PD testing. They also highlight the differences between AC and DC PD testing as well as what you should consider when performing these tests. Lastly, they describe the tools available that make AC and DC PD measurement and analysis easier than before.
