CESC Limited is a power utility providing electricity in 567 sq. km of the Kolkata area in India. More than a century old, it is the nation's oldest power company, dealing with the entire span of electricity business including Generation, Transmission and Distribution. It serves approximately 3 million consumers including domestic, industrial and commercial users.
Operating on a wide range of assets in power generation and distribution, CESC has more than 8,000 distribution transformers in its system, the majority of which are rated between 315 and 500 KVA. CESC has been installing Dry Type transformers in densely populated areas since 1990. Today, around 25% of those assets are Dry Type Transformers. As an alternative to fire prone mineral oil transformers and costly dry type transformers, CESC is considering fire safe and environment-friendly ester oil filled transformers as a possible solution.
TRANSFORMER RETROFILL 1:
Location - Plastic factory in densely populated area(recently installed)
Retrofilling: On-site
Rating of Transformer - 400kva/11/6kV
Application - Fire safety, environmental protection and high temperature operation
TRANSFORMER RETROFILL 2:
Location - Manufacturing workshop, close proximity to a school
Retrofilling: On-site
Rating of Transformer - 400kva/11/6kV
Application - Fire safety, environmental protection and high temperature operation
Aware of its responsibilities to the community and the environment in which it operates, particularly in terms of customer safety and environmental protection, CESC wanted to explore available options for improving the performance of these transformers. M&I Materials was able to advise CESC regarding the option of retrofilling the transformers with MIDEL 7131, a synthetic organic ester offering fire safety and that is readily biodegradable.
