Ultrasonic & Partial Discharge Testing Australia

Ultrasonic and partial discharge testing helps determine the condition of your electrical equipment. At Asset Power, we use the most sophisticated and specialised test equipment available in Australia.  We guarantee our clients the highest levels of safety and quality, helping your business excel.

Transient Earth Voltage (TEV) / Internal Partial Discharge (PD)

This type of testing detects partial discharge (PD) electromagnetic emissions. The emissions can be detected from within the solid insulation materials inside electrical equipment. We use captive coupling technology to detect, locate and measure partial discharge (PD) activity and severity.

Included in our testing service is the measuring, recording and analysis of results. The testing allows us to see trends in asset condition in differing electrical and climatic in-service conditions.

The benefits of TEV and PD testing are:

  • Testing is undertaken online, non-intrusively and safely
  • Extend asset life cycles and maintain peak performance through improved understanding of asset condition

Ultra-Sonic (US) - Surface Partial Discharge (PD)

US and PD testing detect partial discharge (PD) surface emissions (tracking and arching). The discharge and emissions can be detected within the electrical equipment at the location of potential electrical stress.

US and PD testing are done using audio and ultrasonic detection equipment. For example, an airborne ultrasonic sensor or magnetic contact probe focusing around the 40 kHz range. The airborne sensor targets air gaps in the switchgear cabinet where air and emissions can travel out. It can also target the highly sensitive magnetic contact probe on sealed chambers. Other targeting points include:

  • Electrical stress-adjacent equipment
  • Cable terminations
  • Penetrations
  • Structural sharp points
  • Place where conductive and insulating components and materials come close together or in contact
