On-Line PD Testing and PD Mapping (PD site location) of Medium Voltage And High Voltage Cables

IPEC HV utilise the OSM-Longshot© PD Test System and PDGold© Software to carry out On-Line (in-service) PD Testing of Medium Voltage and High Voltage Cables. On-line PD Testing is carried out using a combination of split-core, inductive HFCT sensors (connected around the earth strap or the core of the cable) and capacitive TEV sensors (attached to the cable termination or cable box).

The PDGold© Software automatically differentiates between the captured waveforms of PD pulses and other electrical 'noise' such as thyristor switching and RF noise to provide an instant On-line diagnosis of PD activity.

On-line PD Mapping (PD site location along the lengths of HV cables) is carried out using the OSM-Longshot© PD Test Unit, PDMap© Software and the Portable Transponder from IPEC High Voltage.
