MPD 500

Basic partial discharge measurement and analysis system

Ideal for routine and acceptance testing

The MPD 500 is a basic partial discharge (PD) measurement and analysis system. It includes a clearly-structured pass/fail functionality, enabling user-friendly analysis for routine tests and tests with high throughput. The modular system can be used for single- or multi-channel PD measurements. The MPD software enables full remote control of the measurement devices, detailed visualization of PD measurement data and automated reporting.

MPD 500 at a glance

Meets industry standards
The MPD 500 measures partial discharge in compliance with the IEC 60270 standard to ensure the reliable detection of PD activity in electrical assets.
Low energy consumption
The MPD 500 has an auxiliary battery that provides you with up to 20 hours of uninterrupted operation for continuous partial discharge measurements in the field.
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.
Easy to use
The MPD 500 system’s integrated pass/fail evaluation of partial discharge activity and its customized reporting feature simplifies PD measurement analysis and reporting.

Effective noise reduction

The MPD 500 features effective methods for reducing or eliminating the effect of noise, making PD measurements more reliable and accurate. These include an adjustable center frequency and multiple bandwidths to tune out noise and focus on the test object’s PD signals. 

“Our MPD 500 has a number of automated features that make it ideal for pass/fail partial discharge evaluation during routine and acceptance testing on electrical assets.”
