Using the Sonus PD for Partial Discharge Detection
Partial Discharge (PD) can occur in medium and high voltage switchgear and represents a breakdown between two conducting electrodes. If PD is not detected, the damage to electrical equipment can be catastrophic and cause serious safety events in the workplace. PD can easily be detected with ultrasound and ultrasound inspections should be included in a routine predictive maintenance strategy. This video illustrates how PD can be detected with the use of the Sonus PD handheld ultrasound testing device.
