4. Demand is also a time based value The demand is the average rate of energy use over time The actual label for demand is kilowatt hours hour but this is normally reduced to kilowatts This makes it easy to confuse demand with power But demand is not an instantaneous value To calculate demand it is necessary to accumulate the energy readings as illustrated in the Power Use Over Time figure above 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 The same process is applied to calculate the 15 minute demand value The demand value associated with the example load is 59 68 kWh hour or 59 68 kWd Note that the peak instantaneous value of power is 80 kW significantly more than the demand value The following figure illustrates 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 7 This peak of usage will result in setting a high demand reading For each interval sho

HREE PHASE POWER MEASUREMENT accuracy at frequencies above about 1200 Hz they pass almost no information So when instrument transformers are used they effectively filter out higher frequency harmonic distortion making it impossible to see However when monitors can be connected directly to the measured circuit such as direct connection to 480 volt bus the user may often see higher order harmonic distortion An important rule in any harmonics study is to evaluate the type of equipment and connections before drawing a conclusion Not being able to see harmonic distortion is not the same as not having harmonic distortion 1 4 3 Waveform Capture It is common in advanced meters to perform a function commonly referred to as waveform capture Waveform capture is the ability of a meter to capture a present picture of the voltage or current waveform for viewing and harmonic analysis Typically a waveform capture will be one or two cycles in duration and can be viewed as the actual waveform as a spectral view of the harmonic content or a tabular view showing the magnitude and phase shift of each harmonic value Data collected with waveform capture is typically not saved to memory Waveform capture is a real time data collection event Waveform capture should not be confused with waveform recording that is used to record multiple cycles of all voltage and current waveforms in response to a transient condition EPM6000 MULTI FUNCTION POWER METERING
