Use of the correlation function in on-line measurements of partial discharges of electric motors
Języki publikacji
Abstrakty
Partial discharges accompanying operation of electric motors have a very complex nature. On-line measurements require specialist partial discharge detectors and partial discharge analysing devices. The analysis of signals for diagnostic purposes should be conducted taking into account phase-resolved distributions and mutual correlations between partial discharges and load, temperature and humidity. Together with progressing use of motors, there is a change in the intensity of partial discharges with typical phase-resolved distributions and typical types of correlations. The paper presents results of measurements of partial discharges in industrial motors, including the correlation function, in particular the Pearson's linear correlation coefficient for parameters of partial discharges as well as load, temperature and humidity. Further research in this respect is necessary.
