Meet the new MPD 800 from OMICRON

Electrical Review Logo

OMICRON has introduced its new MPD 800 universal partial discharge (PD) measurement and analysis system.

This latest product represents the next generation of the company’s innovative MPD PD testing technology, which is based on 20 years of MPD customer experience, feedback and an expanding list of requirements for PD testing. Established hardware and software features have been enhanced and new time-saving functionality has been added to make the MPD 800 the most complete, accurate, and flexible solution available for PD testing in a wide range of applications.

Standard-compliant PD testing 

The MPD 800 system performs IEC and IEEE standard-compliant PD measurements and analysis for routine and type testing, factory and site acceptance testing (commissioning), as well as repair testing and troubleshooting in the field. 

With very high measurement accuracy, the MPD 800 system enables users to reliably detect, localise and assess the risk of potentially failure-causing PD activity in the insulation of various electrical assets and components. These include power transformers, rotating electrical machines (motors and generators), power cables, switchgear, and industrial drives, as well as bushings, insulators, capacitors and busbars.

Multi-channel PD measurements

The MPD 800 measurement device includes two fibre-optic input channels for either synchronous, two-channel PD measurements or a single-channel PD measurement plus a gating channel to reduce surrounding interference without the need for an additional device. 

The MPD 800 system can be easily expanded with up to 20 measurement devices connected via daisy chain with fibre optic cables supplied by OMICRON to perform synchronous, multi-channel PD testing at several distributed measurement points. The MPD 800 system software provides users with a convenient overview of all connected devices and the PD measurement data for each measurement channel. 

Customisable user profiles

Users can 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, users can decide which of the available PD measurement and analysis software features they need for a PD measurement, hiding those they do not need at any time for individualised PD testing and reporting. These capabilities make PD testing and analysis much more efficient and easier for users at all skill levels. 

The importance of PD testing 

Insulation faults are a major cause leading to the eventual breakdown and failure of electrical equipment. Therefore, it is crucial that the insulation condition is verified throughout equipment lifecycles. 

Partial discharge is both a major cause and a very reliable indicator of developing insulation defects in electrical equipment. Regular PD measurements allow users to detect and analyse PD activity in the insulation system and to assess the risk and plan maintenance accordingly before major damage or a breakdown occurs.

OMICRON has several years of experience in the field of PD measurement, analysis and monitoring, on both medium-voltage and high-voltage electrical equipment with customers in the asset manufacturing, power utility, industry and service/repair sectors worldwide.
