Rashmi Sanghi is currently working as a scientist at the Facility for Ecological and Analytical Testing, IIT Kanpur. She got her PhD degree in natural products from Allahabad University in 1994 and then carried out postdoctoral work both at IIT Kanpur and at Rutgers University.

Transformer life management [1] is an essential part of a modern power operation system. Oil filled transformer technology has been used for more than 100 years. The principle of operation has not changed over many decades. Many transformers that were built and installed in post World War still remain in service. A properly maintained power transformer can function for 50 to 75 years. However, the maintenance of the insulation system largely determines the extent of a transformer’s life. Future transformers will no doubt have increased capacity and size and their design may require the use of new materials. Transformers may operate at higher temperatures and in turn demand transformer oils of greater stability.
