On-load tap changers (OLTCs) are electromechanical devices used in the voltage regulation of the electrical networks. A non-invasive monitoring method was developed using discrete wavelet transform (DWT) for condition assessment of on-load tap-changers using vibration analysis signals. The transient vibration signals emitted during a tap change are recorded and processed using spectral analysis and...
On-load tap changers (OLTCs) are electromechanical devices used for voltage regulation on electrical networks. A noninvasive monitoring technique was developed using Prony's method for condition assessment of on-load tap-changers using vibration analysis signals. The transient vibration signals emitted during a tap change are recorded and processed using Prony's spectral analysis and standard pre-processing...
