Partial Discharge Measurement and Analysis on Instrument Transformers

Partial discharges (PD), as defined by IEC60270, are localized dielectric discharges in a partial area of an electrical insulation system under high-voltage field stress. Partial discharges in an instrument transformer deteriorate its insulation and can lead to equipment failure.

Diagnostic PD measurements are recommended after conspicuous measured values during factory acceptance testing, on-site acceptance testing and troubleshooting.

You can detect partial discharges already in their early stages with our testing system. This allows you to draw conclusions regarding the condition of the insulation. Maintenance work and additional diagnostic measurements can be efficiently planned based on condition.

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 instrument transformers.

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.
