Partial Discharge Measurement and Analysis –
Avoid the Element of Surprise

April 1, 2019

Detect insulation defects and prevent failure in your electrical assets

After high-voltage equipment has been manufactured and commissioned, it always makes sense to perform on-site partial discharge (PD) measurements on a regular basis during the asset’s service life. PD measurements are performed either offline during planned outages or online while the asset is in service running under regular operating conditions.

Comparing results from consecutive on-site PD measurements provides you with the most reliable information available for determining the insulation condition in electrical equipment. Any change to the phase-resolved PD patterns, or a rapid increase in amplitude, is a sure sign that preventative action needs to be taken.

Additional PD information

Be sure to visit our PD knowledge platform to learn more about PD measurement and analysis. It provides you with videos and short articles about the importance of PD testing as well as the innovative methods used for reliable insulation defect detection in a variety of high-voltage assets. You can also select the best PD testing solution for your application and an OMICRON Academy training course to get hands-on training.
