摘要：An instrument (1) and a method for detecting partial electric discharges involveacquiring a discharge signal (10), for example picked up by a direct- measuring impedancedevice (7) through a broadband HF acquisition channel (18), and acquiring the dischargesignal (10) in a narrowband LF acquisition channel (180) complying with regulations, usingon the LF acquisition channel (180) a trigger controlled in slave mode by a trigger of thebroadband HF acquisition channel (18); they also involve acquiring another dischargesignal (32) picked up by an indirect-measuring impedance device (8) through a secondnarrowband LF acquisition channel (180A) and comparing digital signals (34, 34A)generated in the first and second LF acquisition channels (180, 180A), in order togenerate a balanced digital signal (36) without components representative of commonmode electrical signals present in the measuring circuit.
