Among all the astonishing equipment found in power transmission and distribution networks, the insulator plays a vital role by providing mechanical support and electrical protection to power system. Despite of all these noteworthy facts, the breakdown of insulators owing to surface contaminants appears to be particularly fascinating in today's scientific world. Researchers provide a plethora of methods to eradicate this problem. From all method, superhydrophobic coating provide better solution for its resistance to moisture, wetness, dust and ice. This unique property of superhydrophobic coatings requires further investigation. Hence, the suggested technique achieves this purpose by preparing the eco-friendly superhydrophobic solution of PDMS (Polydimethylsiloxane) with MTMS (Methyl tri methoxy silane) composites. In this study superhydrophobic coating were prepared by using sol-gel method and spray coating technique Analysis like FTIR, surface morphology and coating thermal study were included. self-cleaning ability of superhydrophobic coating on insulator surface with contact angle (CA) was measured from 165° to 170° and sliding angle 5° to 10° confirming superhydrophobic property. Finally, in an intentionally contaminated conditions based on solid layer method of IEC60507 standards and IEC 60587 standards insulation resistance are tested using a megger instrument.

Transformer oil with a petroleum basis has long been used in transformers as insulation and cooling. The environmental concern of the current liquid insulating technique is how spent oil samples are disposed of after extensive use. Due to transformer oil's non-biodegradable composition, which can hurt and contaminate the environment, there is difficulty with disposal. A Nano Particle based Used Transformer Oil Processing Method (NP-UTOPM) is suggested in this research to reuse the used transformer oil in the battery. This work examines the effects of activated bentonite and carbon absorbents in recovering the qualities of used transformer oil by investigating the re-usage features of used transformer oil samples after reclamation treatment. 50ml of used transformer oil is utilized for the reclaiming process, along with separate mixtures of 1%, 3%, and 5%Nano Particles (NP) and blended combinations of two absorbents. According to international regulations, oil sample characteristics such as breakdown voltage, viscosity, dielectric dissipation factor, electrical conductivity, density, specific resistance, surface tension, and temperature properties are tested before and after restoration. The sample of recycled oil is used again as a liquid insulator in batteries.
