Abstract

For preventive diagnosis of HV equipment, different measuring procedures are in use, such as the detection and analysis of PD phenomena as well as the measurement of the capacitance and loss factor. The paper reports on the integration of such different measuring systems to a common, compact and computer based device. This offers for the first time the possibility of a simultaneous measurement of both impedance-parameters of HV insulation and partial discharges. PD faults can be located simultaneously. For analyzing characteristic PD types, a database expert system is integrated. So the global insulation condition can be assessed in a complex manner
