Abstract
A partial discharge detection system including a partial discharge acquisition and processing device includes: a partial discharge detection device configured to provide a detected partial discharge electrical signal from partial discharge pulse generated by a first electrical object; and a first communication module configured to receive a detected synchronization signal carrying detected synchronization phase values and corresponding reference time values associated with an electrical supplying voltage of a second electrical object. The partial discharge detection system further includes: a phase value generator configured to produce synthetized phase values representing a synthetized synchronization signal, the phase value generator being adjustable according to phase errors; and an error computing module configured to compute said phase errors from the synthetized phase values, the detected synchronization phase values and the corresponding reference time values.
