An Electrical Energy Audit of Water Pumping Machines

This is the authors' abstract. We don't add key points for this paper.

The study involves an energy audit of Pumps used to pump fluid from lower level to higher level by using electrical energy. A case study was conducted on centrifugal pumps at Ahmadu Bello University Water treatment plant, series of energy audit was conducted to record various parameters viz., discharge, pressure, voltage, current, power, power factor and efficiencies to calculate the total electrical energy consumption per day and total actual energy use per day, maximum (VA )demand, maximum (KW )demand, consumption figures of the whole pump in the plant, energy cost figures of the plant in (KWh), where we discovered very high energy wastage during operation .Therefore ways to reduce energy consumption by the replacement of the present pumps with inverter compatible energy efficient pumps and various conservation methods are recommended for optimum utilization, this study will help other pumping stations.
