    Abstract: This study presents an in-depth analysis and evaluation of the amount of voltage drops in houses along selected streets in Benin city, which was restricted to Power Holding Company of Nigeria (PHCN). The study embraced the readings of the transformer supplied voltage, house-to-house received voltage, currents, power consumption in each house using clip-on metre, while the distance of each house from the transformer supplying, the street was obtained using measuring tape. The results obtained shows that if consumers are to receive a reasonable supplied voltage for efficient operation of their appliances the distance of the consumer’s service cable at the farthest end from the transformer should not exceed 400 m.
