Partial discharge (PD) is a very reliable indicator of potential failure-causing faults in electrical equipment insulation. Regular PD testing and PD monitoring are used to reliably assess insulation condition throughout equipment lifetime. In this episode, two of OMICRON’s PD experts – Patrick Zander and Samuel Scheller – describe the differences between PD testing and monitoring, when they are used and how they complement each other.

Show Notes:

PD testing and monitoring play a critical role in assessing insulation condition, focusing maintenance efforts and preventing the pre-mature failure of electrical equipment, such as power transformers, generators, motors, switchgear and power cables.

There are various methods of PD testing and monitoring, but when is each method ideally used to detect potential failure-causing insulation defects? What are their differences and how do they complement each other?

To answer these questions and to offer some insight on this topic is Patrick Zander, a specialist in PD testing and monitoring at OMICRON, and Samuel Scheller, the OMICRON product manager for PD monitoring solutions.
