Transformer Total Cost of Ownership

This month’s Featured Technical Paper is from the Proceedings of the 2018 International Conference of Doble Clients. The paper is titled: Transformer Total Cost of Ownership.


This paper will discuss the Total Cost of Ownership (TCO) for the life of a transformer within National Grid. Many factors that require consideration prior to entering into the bidding process of buying transformers are explored in this paper. National Grid recognizes that when evaluating proposals many other factors, in addition to purchase price, need to be taken into consideration to determine the true cost of the asset over its expected service life. Currently, National Grid only includes the losses over a thirty year term. This paper will discuss factors such as maintenance activities, trouble records, failure rates, refurbishment and other indirect costs that should be included in the TCO model to calculate the true cost of the asset. Using this model will enable us to compare multiple proposals on a common basis. The TCO model is a valuable tool that allows the best selection of a transformer for optimum savings over the life of its ownership.
