Before we discuss on any of the previously stated factor, let us first define some important terms the we should be familiar with: LOAD GRAPH/CURVE - is a graphic record showing the power demands for every instant during a certain time interval. The area under the load curve is equal to the energy or kW-hr delivered to the particular load. CONNECTED LOAD - The connected load on any system or part of the system is the combined continuous rating of all the receiving apparatus on the consumer's premises that is connected to the system under consideration. DEMAND - it is the load usually expressed in kW, kVA averaged over a suitable and specified interval of time of short duration. MAXIMUM DEMAND or PEAK LOAD - is the greatest of all the demands that have occurred during a given period. It is measured according to specifications, over a prescribed time interval during a certain period such as a day, a month, a year. AVERAGE LOAD - it is defined as the average demand dur
