Distribution system losses calculated by percent loading

The energy and demand losses of distribution systems can be calculated by using the percent loading on the different components of the distribution system. The systemwide energy flowing through a distribution component is divided by the systemwide energy-handling capacity of the component for the period of time the losses are to be calculated. This percent loading, along with the simple surveys and plant accounting records of the distribution system, is used to find the losses. The method uses simple calculations, readily available data, and solves system losses directly. >
