Can Ultrasonic PD Detection Be Carried Out Non Intrusively on MV Switchgear?

Partial Discharge Detection, Partial Discharge Testing / By

The effectiveness and safety of power distribution networks substantially depend on the correct operation of electrical equipment, including medium-voltage (MV) switchgear. Partial discharge (PD) is the most well-known hazard to the reliability of these systems. PDs, or localised dielectric breakdowns, are triggered by factors like high voltage, moisture, insulation faults, or even mechanical damage to …

Partial Discharge Testing: Online And Offline Partial Discharge

Partial Discharge Testing / By

Partial discharges are small discharges that take place between two electrodes. These minor discharges primarily occur in a few select areas around the insulation. Unbalanced electrical stress may be the root cause of these partial discharges. Catastrophic failures could result from these undetected partial discharges.  There are techniques to detect these partial discharges before failure …
