Title: Applicability of the Dielectric Response Methods for Diagnostics of Power Transformers by Application of Return Voltage Measurement
Abstract: The remaining life of a transformer is significantly influenced by the condition of the impregnated paper. Recent attention has been directed to spectrum methods of assessing moisture and ageing by-products in the transformer insulation. The applicability of the spectrum methods is discussed and recommendations are given how to improve the interpretation of results with special attention to the return voltage technique. These methods are particularly useful for transformers therefore it is too surprising that a real guide or standard is missing. Going into details it is not the goal of this paper, here we would like to clarify some anomalies and show a possible interpretation of results measured with the return voltage technique.
