Partial Discharge Portable Tester

PD Detector

The PD Detector is an on-line partial discharge (PD) spot tester for HV assets. The instrument detects TEV signals generated by internal discharge in Air Insulated Switchgear (AIS), acoustic discharge generated by surface tracking or corona, high-frequency signal generated by cable partial discharge, and ultra-high frequency signal generated by internal discharge in Gas Insulated Switchgear (GIS). A mobile device receives data directly from the instrument for display and synchronisation with a central server.

  • Data synchronisation to central server
  • Log and trend PD activity against particular assets
  • Data integration with asset management systems

Partial Discharge Portable Tester

PrecisePD

PrecisePD is an on-line Partial Discharge Spot Testing and Location System for Cables and Switchgear with advanced signal processing, used for the detection of PD in high noise environments. PrecisePD allows users to investigate and locate Partial Discharge sources on live electrical equipment, helping to prevent potential faults in high voltage assets. Designed by IPEC Ltd, the PrecisePD Spot Tester takes advantage of the many years of IPEC’s field experience. Using the advanced DeCIFer (designed to operate in high noise environments) the unit offers significant advantages over many other Spot Testing systems.

  • Sensitive PD detection in high noise environments
  • Test cables up to 4km in length
  • Accurate Cable PD Mapping for defect location

 ipec pd-sg1

Partial Discharge Portable Tester

PD-SG1

The PD-SG1 is a dual transducer Switchgear PD detection instrument. The unit detects TEV signals generated by internal discharge, as well as acoustic discharge generated by surface tracking or corona. Partial discharge activity inside metal clad high voltage plant induces small voltage impulses (called Transient Earth Voltages) on the surface of the metal cladding. TEVs travel around the cladding surface to the outside of the switchgear panel, where they can be picked up externally using capacitively coupled transducers.

  • Ultrasonic detection of surface PD activity, displayed on the LCD screen as dB reading
  • Measurement of TEV signals generated by internal PD
  • Cycle Mode for viewing PD pattern in power cycle (Phi Q), allowing for the elimination of noise
