From the time of the measurement that is one minute and since we specify that the load is constant increase in a minute, we can convert the power reading to an equivalent reading of energy consumption to 1/60 time by multiplying the power reading (converting the time base from minutes to hours). Demand also is a value based on the time. The demand is the average energy used at a certain time. The current label for demand is kilo watt-hours/hour but this is normally reduced to kiloWatts. This makes it easy to confuse with power demand.

But the demand is not an instantaneous value. To calculate the demand it is necessary to accumulate the energy readings and adjust energy readings to a time value that constitutes the demand. To convert the reading to a value of demand, should be normalized to the range 60 minutes. If the pattern was repeated for additional intervals, three intervals of 15 minutes, the total energy would be four times the measured value or 59.68 kWh. The same process applies for calculating the value of the demand for 15 minutes. The demand value associated with the load of the example is 59,68 kWh/hr or 59,68 kWd. Note that the maximum instantaneous value of the power is 80 kW, considerably more that the value of the demanda.Como can give account, is important to recognize the relationship between power, energy and demand in order to effectively control loads or to properly monitor its usage, is for this reason that I would like to recommend the proper use of measuring instruments electric, especially an Analyzer of wave quality with which we can be sure of the quantity and quality of energy flowing through our computers.
