Condition assessment of insulation is widely used to identify the state of aging of power transformers. Traditionally, condition assessment is done using dielectric response measurements conducted at low frequencies. However, due to long testing time

Increased moisture content (MC) is considered as one of the main factors for the failure of transformer insulation. This paper presents a method of estimating the MC of a transformer pressboard insulation based on the relative permittivity and loss t

Corrosive sulphur compounds in mineral oil can react with the copper and silver surfaces in a power transformer which has been known to lead to failure. The metal sulphide layer may break off and be carried around the transformer by the flow of oil,

Transformer oil is one of the essential insulation medium used in power transformers. During transformer operation oil may expose to various stresses such as electrical, thermal, chemical etc. As a result electrical properties of the oil may be degra

Measurement of dielectric properties of copper clad printed circuit boards using microstrip ring resonators is a well-studied problem widely in use. The problem addressed here is different from this as the sample under test is difficult to copper cla
