Abstract

Since small distribution transformers fail in a stochastic fashion, the exact time of failure is not known. If the cost of replacing an unfailed transformer is less than the cost of replacing a failed transformer it is advantageous to replace the transformer before failure (preventive maintenance). Using preventive maintenance theory, a method that minimizes the cost of owning a small distribution transformer is developed. The costs taken into account in the method are the capital cost of the transformer, revenue generation by depreciation, replacement costs, and operating costs of the transformer.
