Welcome toThe Partial Discharge Academy

Partial Discharge Location & Quantification

The location of a Partial Discharge site can be identified quickly and accurately by using an instrument which employs two capacitively coupled probes, 600mm or more apart, to measure TEV signals. The instrument calculates the time of flight variations between discharge pulses as they reach the two probes and in turn indicates the source of the discharge in relation to the probes. Using this method, the source of PD activity can be identified to an accuracy of 0.33ns (nanosecond), equivalent to 10 centimetres.


PD Location & Quantification
The location of Partial Discharge Activity can be identified using time-of-flight measurement between two probes on enclosures, or with a directional microphone on overhead assets



Used in single probe mode, TEV-based instruments will measure the magnitude of the discharge.
