Power transformers are a key component of electrical networks, and they are both expensive
and difficult to upgrade in a live network. Many utilities monitor the condition of the …

The dielectric modulus M*(ω) is used for studying the frequency domain response and
activation energy (E a) of transformer immersed cellulose insulation. Existing literatures …

In this work, samples of oil-immersed paper with different moisture levels and aging
condition were studied. Frequency domain spectroscopy (FDS) of the samples was …

The life expectancy of power transformers is primarily determined by the integrity of the
insulating oil and cellulose paper between the conductor turns, phases and phase to earth …

In this work we have developed low-cost, renewable and sustainable materials based on
cellulose for electronic applications. The UV–Vis spectroscopy, water contact angle and …

An expensive power system component, transformers play a crucial role in power systems.
Among the parts of transformers whose health status may affect their performance is oil …

This study describes a low‐cost sensor‐based scheme for online moisture measurement in
transformer oil. Considering a harsh environment, moisture measurement of oil at ppm level …

Oil‐immersed bushing is one of the most important accessory equipment of a transformer,
whose insulation status is crucial. Moisture is an important factor that affects the insulation …

It is necessary to study the micro mechanism of water diffusion behavior at the liquid-solid
interface between natural esters and cellulose by adding nanoparticles to natural esters, the …

Thermal stress and moisture absorption can cause a synergetic negative impact on kraft
paper. Among various approaches for improving the dielectric properties of kraft paper …
