Other advantages of the eco friendly power transformer include lower noise levels, reduced ageing, increased fire safety as well as reliability. For instance, the level of noise reduction above 10 dB (A) is made possible due to a combination of things such as the selection of materials which tend to deliver a higher performance and equipment, along with the optimised design of active parts and innovative mechanical structures as well.
In terms of its safety and reliability, the environment friendly transformer generally offers an increase in shelf life while being safe. By using a Green Power environment friendly transformer, fire safety is an aspect that has been improved considerably. Thus, these green transformers not only offer an increase in security, for operators but also for those in close proximity. Ester oil has a fire point above a temperature of about 350 degree C, which is more than two times as high as compared to mineral oil.
Green or environmentally friendly transformer oil, on the other hand tend to be less flammable and are also known to aid in the reduction of fire spreading.In order to further maximise operational management in addition to preventing faults and damages, an advanced on-line monitoring systems could also be added to these transformers.
In arrange to meet the current and future energy challenges, there’s require for an energy efficient, market effective, grid reliable and environment friendly technology.The reply to these concerns came forward in Green Transformer concept that contains modern advances and materials in regard of fixing, cooling and protection, exchanging (tap changer) as well as control and predictive observing connected to Smart Grid technologies.The transformer offers to be eco-friendly, by limiting the carbon footprints for its shoppers. For occurrence, the oil utilized in such transformers is Ester oil produced from vegetables rather than the ordinary mineral oil; Easter oil has been rumored for their eco-friendly properties additionally for a high flash point of up to 350 degree C.

Ester liquids have been utilized in transformers for separator and cooling purposes for over 20 years. These liquids incredibly decrease natural affect and essentially moderate spillage and fire dangers. Recent experience underlines the benefits of utilizing ester liquids rather than conventional mineral oils.
