Condition assessment of power transformer onload tap changers using wavelet analysis and self-organizing map field evaluation.

Condition assessment of power transformer onload tap changers using wavelet analysis and self-organizing map field evaluation.

An onload tap changer (OLTC) is the most maintenance intensive subassembly on a power transformer. Vibration monitoring is an effective technique that can be used to assess the condition of an OLTC nonintrusively. The authors have developed a condition monitoring system for common types of OLTCs tha...
