#CMT# #/CMT# The method involves computing corresponding time constants from the measured return voltage curves by adopting a course with regard to a Maxwell-model of two resistor capacitor-parallel elements point wise from three points of the curve. The diagnosis parameter is formed as product of the logarithms of the time constants for characterizing the deterioration or degradation condition of the insulation system. #CMT#USE : #/CMT# Method for characterizing the insulation condition of high voltage-power transformers in frame of the methods of the return voltage measurement. #CMT#ADVANTAGE : #/CMT# The method involves computing corresponding time constants from the measured return voltage curves by adopting a course with regard to a Maxwell-model of two resistor capacitor-parallel elements point wise from three points of the curve, and hence ensures improved and accurate characterization of the insulation condition of high voltage-power transformers. |
