What is mean by load curve in electrical engineering
Chronological Curve There is an average load on the power station in a given time period which could be set depending on the load variation If this load on the power supply station is plotted against the time periods in which these loads occur it gives rise to what is known as the chronological curve because of the chronological appearance of the power demand along the time sequence
