Continuous updates for optimized performance Since we launched our latest-generation MPD 800 and UHF 800 systems, we’ve released a new software update each year. These updates included original features that were greatly enhanced, and new capabilities were added to optimize the overall performance and extend the available toolset to help users accomplish a wide variety of testing needs. Some of these significant enhancements included the following: › Very-Low Frequency (VLF) PD Testing MPD Suite software updates have greatly simplified PD testing with Very-Low Frequency (VLF) test voltages in the 0.1 Hz or 0.01 Hz range. VFL PD testing on power cables is easily performed with one click of a mouse rather than manually as before. › GPS-synced PD datasets For PD testing applications on power cables where it is impossible to lay fiber optical cables, PD datasets are recorded with two or more MPD 800 systems at different positions along a power cable, such as joints or terminations. These PD dataset files can be merged for postanalysis and PD localization. They’re displayed as one file when replaying the recorded data. This not only simplifies reporting but also allows users to perform PD localization. › Automatic PD event triggered trending This feature supports users when triggering conditionbased measurement actions. Now, creating automatic PRPD screenshots and recording dataset files is possible when certain conditions are met. These include conditions such as repetition after a certain time interval, a measurement reading exceeding a configurable threshold for a certain time, or a certain minimum number of PD pulses appearing in the PRPD in a certain place. This allows unsupervised PD measurements during commissioning or prolonged PD tests without overlooking critical events. › IEC 60270-compliant performance check for MPD 800 The IEC 60270 standard, which forms the basis for most PD measurements, mandates that PD measurement devices undergo a performance check once per year. This check ensures that the PD filters used in those measurement devices continue to operate correctly. The MPD Suite software (starting with Version 1.50) now includes a Performance Check Wizard, which automates this process for MPD 800 devices. It guides users through the necessary measurements, collects data results, compares them with results from previous measurements, and reports whether all MPD 800 devices comply with the limits outlined in the IEC 60270 standard. As a result, users no longer need to send their MPD 800 devices to a calibration lab or spend a lot of time performing tedious measurements.

This feature is useful for a variety of applications, including detailed pulse shape analysis on all assets or triggering acoustic PD localization with PDL 650 via the MPD 800 optical output.
