Making Partial Discharge data analysis easy and accurate

To effectively understand and prevent partial discharge in high voltage systems, it is crucial to prioritise phase lock. This can lead to improved data analysis and better informed decision making. Fortunately, a new wireless phase reference accessory has been introduced to ensure accurate phase lock in any environment.

Have you ever heard of a phase lock?

A phase lock is applied while recording PRPD (phase resolved partial discharge) patterns to ensure data quality.

It effectively matches the frequency of your test instrument to the typical 50/60Hz frequency of the HV network, whilst conducting PD tests.

As PD occurs, it will generate discharges or events that can be captured and plotted along one cycle of a 50/60Hz sine wave, creating a pattern which can be interpreted.
