Among effective techniques to evaluate the installation cost is to make your investment decision based on what's called the "total cost of ownership",
Total cost of ownership for a transformer accounts for both the purchasing (initial) cost of the transformer as well as for the operational costs.
The losses can be divided into two categories: load losses, which are proportional to the transformer load (square of current); and no-load losses, which are caused by the magnetization of the core as long as the transformer is energized, and are constant - independent of the transformer load.
A high efficiency transformer corresponds to equipment designed for low level of losses to ensure reduced cost of ownership for end user, in addition it contributes positively to environment sustainability.
