Wide-Band Partial Discharge Detector

A wide-band peak voltage detector is presented, which is used for measuring partial discharges in submarine telecommunication cable systems. For high-voltage discharge detection of simple dielectric geometries or complete power filters, the wide-band detector is suitable for laboratory or factory use. A low-cost low-resolution amplitude-distribution analyzer can be assembled by combining several detectors for the special requirements of high-voltage dc testing, at a small fraction of the cost of a commercial distribution analyzer.
