Partial discharge measurement

Partial discharge measurements are becoming increasingly important for quality inspection and condition assessment in high voltage insulation. In many cases, these nondestructive testing methods are the only practical type of diagnostics possible.

With our experience in the development and use of various PD measurement technologies, we are your expert partner and advisor when selecting appropriate technology for your testing needs. We offer a variety of PD measurement and monitoring equipment, as well as special calibrators for calibrating the standard PD measurement circuit to determine the apparent charge.

On-site partial discharge testing frequently uses unconventional measurement technology in the higher frequency range (HF and UHF). The use of such sensors often eliminates the need to shut off the operating equipment, since this measurement method does not require galvanic coupling to the high voltage conductors. The stronger attenuation of more distant signals also allows for more favorable signal/noise ratios and locally selective PD tests.

We offer UHF measurement technology, a variety of sensors, and UHF signal injectors.
