Dielectric response analysis, performed in time domain and frequency domain is one of the
interesting methods used for condition assessment of high voltage equipment. In this article …

Conductivity is an important parameter which has definite correlation with the amount of
moisture present within the transformer insulation. However, in existing methods conductivity …

The excitation used in the CV characteristic measurement is a combined voltage of high-
voltage direct current (HVDC) and low-voltage alternating current (LVAC). Under the …

The current time domain spectroscopy of dielectrics provides important information for the
analysis of dielectric properties and mechanisms. However, there is always interference …

As the main insulating material of an ultra-high voltage (UHV) resin impregnated paper (RIP)
bushing, epoxy resin accumulates space charge under the DC voltage, which would affect …

This study investigates electron emission from copper broad-area emitters (CBAEs) and
copper broad-area composite emitters (CBACEs) based on the principles of trapping and …

The insulation system in a power transformer is basically comprised of oil and oil-
impregnated paper. The lifetime of power transformer is very much dependent on the …

Inorganic insulating powder can potentially be used in nuclear power plant cables, fire-
resistant cables, and so on due to its high heat resistance and radiation resistance. It is of …

This paper puts forward a novel approach to evaluate an equivalent circuit of oil paper
insulation used in transformers from frequency domain spectroscopy measurements. In …
