Case Studies Of The Transformers Failure Analyses
Collection of failure data is the first major task. In free repair service or in repair contract, very little effort is made by utilities to find out the root cause of failure, which could be one of the reasons why a damaged transformer is replaced by a new one without removing the cause of damage, leading to failure immediately or within a very short period... - Manish N Sinha, Palak Patel, Parth Shah, Maulik Doshi, Nishith Bhalodiya

Typical Phenomena in Transformers & Protections
An analysis of the current during an over excitation condition shows a predominant 5th harmonic component while analysis of inrush current shows a predominant 2nd Harmonic component. These characteristics help to differentiate an over excitation condition from inrush current condition. - Rajesh Chourishi
Curse of Dual Certification for Distribution Transformers
There is a conflict, the manufacturers are requesting Govt. of India to allow them the compliance of one of the authorities/ agencies directive i.e. BIS or BEE for the same goal of producing Energy Efficient DTs, and should not insist upon as in both the cases, they have to manufacture Energy Efficient Distribution Transformers as per only one standard IS:1180 Part 1/2014… - B Lal
