In numerous applications, this non-destructive test method is even the only meaningful type of diagnosis. Thanks to our experience in the development and application of various PD measurement technologies, you will find us to be a competent contact and advice on the selection of suitable technology for your testing task. We offer various partial discharge measuring and monitoring devices as well as special calibrators to calibrate the standard TE measuring circuit to determine the apparent charge. For partial discharge tests on site, unconventional measurement technology in the higher frequency range (HF and UHF) is often used. Switching off the equipment can often be avoided with the use of appropriate sensors, since this measuring method does not require a galvanic coupling to the high voltage. The greater attenuation of signals that are further away also enables more favorable signal-to-interference ratios and location-selective PD tests.
