A new multi-purpose partial discharge analyser for on-site and on-line diagnosis of high voltage components

This paper reports on a solution for online partial discharge (PD) testing. The possibilities of a standard digital detector for offline PD testing have been extended by tools for online PD recording according to the VHF/UHF PD detection technique. The development of the measuring system aimed at realization of modern technologies in a flexible solution, while keeping the familiarity of the functions of the original detector intact.
