Abstract :
HEAVIER LOADING of distribution transformers offers significant operating economies, but it seems unwise to increase loading substantially without a realistic appraisal of its probable effect on life expectancy. Also, the development of new insulating systems offers potential economies, but the magnitude of the savings cannot be determined until the relative life expectancy of the new systems is determined.
