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

Typically the curve looks something like the one below A is the maximum t 10 value achieved This is significant for higher energy breakage The absolute value of A is not critical in a SAG mill because it is a measure of the breakage of the ore at energy levels higher than those that are usually achieved in a SAG mill
