India, Mumbai: Adani Electricity Mumbai Ltd (AEML) recently commissioned India’s first synthetic ester oil-filled 220 kV, 125 MVA capacity power transformer.
Supplied by Siemens’ Kalwa works, the green transformer was commissioned in Mumbai transmission network in a record time of 15 days.
Unlike conventional mineral oil filled transformer, synthetic ester oil transformer has higher fire point (>300 °C), low heat of combustion (30.8 MJ/kg). Moreover, it offers enhanced fire safety, better performance at higher temperature and prolonged life of Insulation paper, and consequently of the transformer itself.
Further, its oil has better biodegradability which is an environment friendly. Considering this, ester oil transformer is best suitable for city like installation. Along with that it has another additional feature such as resin impregnated paper (RIP) bushings, vacuum OLTC (on load tap changer), which improves reliability, significantly.
Speaking on the occasion AEML’s spokesman said, “The Installation of ester oil-based transformer once again underlines AEML’s commitment for greener future of the city. AEML is already committed to supply 30 % of total electricity in its licence area through renewable resources.”
An integrated power utility with presence in generation, transmission and distribution in Mumbai, AEML’s transmission division operates eight 220 kV extra high voltage substations with an aggregate transformation capacity of 3,250 MVA. Five out of these are new-technology vertically designed, compact gas insulated switchgear based EHV substations.
