Device for locating spark discharge in electrical equipment e.g. electrophotographic printer, for printing paper web, has evaluation unit evaluating signals to determine comparison values, where spark discharge is located based on values

The device has antennas (58, 60, 62) arranged at electrical equipment (20). An evaluation unit (64) is coupled to the antennas, and evaluates signals to determine comparison values. An electromagnetic wave is generated by spark discharge in the electrical equipment. The comparison values are represe...
