Condition assessment of power transformer on-load tap-changers using wavelet analysis.
The operation of a power transformer on-load tap-changer (OLTC) produces a well-defined series of vibration bursts as its signature. Due to the harmonic and nonstationary nature of the transient vibration signal, traditional frequency and time-frequency techniques are on longer effective for charact...
