Environmentally Friendly Fire Safe Superior Synthetic Ester Dielectric Fluids for Green Transformers
Subscribe/Renew Journal
Electricity is the engine powering the economic development and growth of any country. Transformer is the most vital equipment in the application of the electrical energy for diverse needs like domestic, indoor and outdoor distribution, high voltage, extra high voltage and ultra-high voltage applications. The transformers and reactors are critical links in the transmission and distribution systems. Over the period rapidly expanding power transmission systems involving HV, EHV & UHV equipments, have seen vast changes in the material concept and designs also. Today we have an installed capacity of electricity is 330.86 GW as of 22 December 2017, and we find thousands of transformers are ubiquitous in human environment. Added to it in today’s overriding concerns about environment and fire safety compact transformers capable of taking higher loads, electrical & thermal stress and meeting environmental requirements are increasingly in use.
Distribution transformers are very crucial parts of transmission & distribution domain these units require dielectric fluids which ensure excellent performance and absolute safety. The synthetic ester based dielectric fluids having extraordinary properties are ideal for these power equipments.
In this paper we present the results of the study undertaken by us on a vastly superior synthetic ester dielectric fluid in accordance with IEC 61099, 61125 Method C, OECD 301B & IEEE C57.104
