One of the central tasks pursued by the lab team rests in investigating modern advanced methods for detecting partial discharges in power equipment (typically transformers) via monitoring the electromagnetic emission in the ultrashort wave band (300 MHz - 3 GHz). The approach facilitates determining the severity of their discharge activity and localizing the critical point of origin at a high degree of accuracy. The team have developed a unique diagnostic system that is used in the operational diagnostics of transformers at the Dukovany nuclear power plant.
