Twenty-five years ago, a partial discharge (PD) measurement technology that could provide real-time, geographically distributed, and highly sensitive PD measurements at multiple unsupervised sites didn’t exist. This led to the development of fiber optic connections, synchronized, multi-channel PD measurements, and the ability to record all PD data in realtime for post-analysis. These requirements were the impetus for MPD development, which began in 2000 and resulted in product solutions, like the MPD 540 in 2003, the MPD 600 in 2007, and the MPD 800 in 2020. Ground-breaking PD testing technology Today, MPD technology offers a highly compact and complete solution, making PD testing available to all types of users. It enables a quick and easy setup that only requires minor training, maintaining complete IEC 60270 standardcompliant and fully traceable PD measurements with the kind of quality documentation users require. MPD technology also has advanced functionality that helps specialists and experts solve the most complex challenges on-site and in the lab. We followed our latest MPD 800 PD measurement and analysis system in 2022 with the UHF 800 for ultra-high frequency range PD testing for testing environments with high levels of external noise. They both feature the latest PD measurement technology, including two PD measurement channels, optimized filtering for highly effective noise suppression, and reliable PD source separation techniques. In addition, users can customize testing profiles by only selecting the PD measurement and analysis features they need for the type of test they’re performing. THE NON-STOP PROCESS OF MPD TECHNOLOGY DEVELOPMENT Continuous MPD 800 optimization is driven by innovation and listening carefully to our users. 28
