Sažetak

Transformers such as HV/EHV (132 kV and above) are the most vital and costly equipment in power systems and large Industries. It is the prime duty of HV/EHV substation managers, asset managers, and substation Operation & Maintenance (O&M) engineers to look after transformers, beginning from receipt on-site through their lifecycle scrupulously with motherly feelings.
Generally, OEM (Original Equipment Manufacturer) guidelines must be followed. This article by K. K. Murty, J. J. L. Kapil, Santosh Dubey, S. K. Chaturvedi is a contribution of experienced engineers in O&M and testing and commissioning up to 400 kV in HV/EHV substations. The authors deliberate all the aspects from receiving the consignment of an EHV Transformer on-site through its lifecycle, including O&M and life expectancy enhancement.
This third part of the article serves as a guideline for substation managers, asset managers, and substation engineers in the absence of any guidelines issued by their utilities or in the industry.
