To calculate demand it is necessary to accumulate the energy readings as illustrated in Figure 1 7 and adjust the energy reading to an hourly value that constitutes the demand In the example the accumulated energy is 14 92 kWh But this measurement was made over a 15 minute interval To convert the reading to a demand value it must be normalized to a 60 minute interval If the pattern were repeated for an additional three 15 minute intervals the total energy would be four times the measured value or 59 68 kWh EPM 9900 MULTI FUNCTION POWER METERING SYSTEM USER GUIDE 1 9 1 10 CHAPTER 1 THREE PHASE POWER MEASUREMENT The same process is applied to calculate the 15 minute demand value The demand value associated with the example load is 59 68 kWh hr or 59 68 kWd Note that the peak instantaneous value of power is 80 kW significantly more than the demand value Figure 1 8 shows another example of energy and demand In this case each bar represents the energy consumed in a 15 minute interval The energy use in each interval typically falls between 50 and 70 kWh However during two intervals the energy rises sharply and peaks at 100 kWh in interval number 7 This peak of usage will result in setting a high demand reading For each interval shown the demand value would be four times the indicated energy reading So interval 1 would have an associated demand of 240 kWh hr Interval 7 will have a demand value of 400 kWh hr In the data sho

16. N 1 meter elements will measure the power or energy taken provided that all the potential coils have a common tie to the conductor in which there is no current coil Three phase power measurement is accomplished by measuring the three individual phases and adding them together to obtain the total three phase value In older analog meters this measurement was accomplished using up to three separate elements Each element combined the single phase voltage and current to produce a torque on the meter disk All three elements were arranged around the disk so that the disk was subjected to the combined torque of the three elements As a result the disk would turn at a higher speed and register power supplied by each of the three wires According to Blondel s Theorem it was possible to reduce the number of elements under certain conditions For example a three phase three wire delta system could be correctly measured with two elements two potential coils and two current coils if the potential coils were connected between the three phases with one phase in common In a three phase four wire wye system it is necessary to use three elements Three voltage coils are connected between the three phases and the common neutral conductor A current coil is required in each of the three phases In modern digital meters Blondel s Theorem is still applied to obtain proper metering The difference in modern meters is that the digital meter measures each phas
