Partial Discharge Measurement and Analysis on Power Cables

Partial discharge (PD) phenomena are local dielectric breakdowns of a small portion of electrical insulation that is subjected to high-voltage stress.

PD can be the result of internal weak spots in power cables, such as voids, cracks or particles. It is also caused by damage to the outer semi-conductive layer of cables or to joints and terminations during installation.

PD measurement and analysis based on IEC 60270, IEC 60840 and IEC 62067 standards are an importance means of inspecting the insulation quality of power cables and cable accessories during manufacturing, on-site cable commissioning (acceptance testing) and troubleshooting when in service.

Customizable user profiles

You can easily define individual test specifications, including calibration and measurement settings, based on applicable international standards for specific types of PD tests and test objects, and save them as profiles for current and future use. In addition, you can decide which of the available PD measurement and analysis software features you need for a particular PD measurement, hiding those you do not need at any time for individualized PD testing and reporting.

Benefits of this solution

Meets industry standards

The MPD 800 measures partial discharge in compliance with the IEC 60270 standard to ensure the reliable detection of PD activity in power cables.

Safe operation

Maximum operator safety is ensured with fiber optic cables, which enable complete electrical isolation between the user, computer, recording unit and the test object.

Reliable noise filtering

The MPD 800 provides you with a free choice of measurement frequency and bandwidths to maximize measurement sensitivity in environments with high interference.

Advanced analysis tools

The MPD 800 uses advanced graphical tools, such as 3PARD (3-Phase Amplitude Relation Diagram), to separate multiple partial discharge sources for reliable fault detection.
