Partial Discharge Detection with High‐Frequency Band through Resistance–Temperature Sensor of Hydropower Generator Stator Windings
In order to improve the signal to noise ratio for partial discharge (PD) detection using a resistance–temperature detector laid in the stator windings of a hydropower generator, the continuous wavelet transform (CWT) is applied as a kind of time‐frequency analysis. Relying on the combination of freq...

Relying on the combination of frequency resolution and time resolution using an applied power voltage phase angle distribution, PDs occurring in voids of stator windings are expected to be found within a mixed environment of strong noise and confusable noise. Furthermore, we found that the CWT may make it possible to calibrate the PD charge quantity in a band of a few tens of MHz under favorable conditions, where calibration is usually difficult for generator stator windings. | ||

Partial Discharge Detection with High‐Frequency Band through Resistance–Temperature Sensor of Hydropower Generator Stator Windings |
| abstract |
In order to improve the signal to noise ratio for partial discharge (PD) detection using a resistance–temperature detector laid in the stator windings of a hydropower generator, the continuous wavelet transform (CWT) is applied as a kind of time‐frequency analysis. Relying on the combination of frequency resolution and time resolution using an applied power voltage phase angle distribution, PDs occurring in voids of stator windings are expected to be found within a mixed environment of strong noise and confusable noise. Furthermore, we found that the CWT may make it possible to calibrate the PD charge quantity in a band of a few tens of MHz under favorable conditions, where calibration is usually difficult for generator stator windings. |
