    Digital Energy Multilin EPM 2200 Multi-function Power Metering System Chapter 1: Three-Phase Power Measurement Three-Phase Power Measurement This introduction to three-phase power and power measurement is intended to provide only a brief overview of the subject. The professional meter engineer or meter technician should refer to more advanced documents such as the EEI Handbook for Electricity Metering and the application standards for more in-depth and technical coverage of the subject.
  • Page 6 CHAPTER 1: THREE-PHASE POWER MEASUREMENT FIGURE 1–1: Three-phase Wye winding The three voltages are separated by 120 electrically. Under balanced load conditions with unity power factor the currents are also separated by 120 . However, unbalanced loads and other conditions can cause the currents to depart from the ideal 120 separation.

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT The following table indicates the common voltages used in the United States for wye connected systems. Table 1–1: Common Phase Voltages on Wye Services Phase-to-Ground Voltage Phase-to-Phase Voltage 120 volts 208 volts 277 volts 480 volts 2400 volts 4160 volts 7200 volts...

In a true delta service, the phase-to-ground voltage will usually not be balanced because the ground is not at the center of the delta.

  • Page 10 CHAPTER 1: THREE-PHASE POWER MEASUREMENT In modern digital meters, Blondell's Theorem is still applied to obtain proper metering. difference in modern meters is that the digital meter measures each phase voltage and current and calculates the single-phase power for each phase. The meter then sums the three phase powers to a single three-phase reading.

  • Page 12: Power, Energy And Demand

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT Power, Energy and Demand It is quite common to exchange power, energy and demand without differentiating between the three. Because this practice can lead to confusion, the differences between these three measurements will be discussed. Power is an instantaneous reading.
  • Page 13 CHAPTER 1: THREE-PHASE POWER MEASUREMENT The data from Figure 1-7 is reproduced in the table below to illustrate the calculation of energy. Since the time increment of the measurement is one minute and since we specified that the load is constant over that minute, we can convert the power reading to an equivalent consumed energy reading by multiplying the power reading times 1/60 (converting the time base from minutes to hours).

  • Page 14: Demand

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT 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.
  • Page 15 CHAPTER 1: THREE-PHASE POWER MEASUREMENT Intervals (15 mins.) FIGURE 1–8: Energy Use and Demand Intervals As seen in this example, it is important to recognize the relationships between power, energy and demand in order to effectively control loads or to correctly monitor use.

  • Page 16: Reactive Energy And Power Factor

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT Reactive Energy and Power Factor 1.3.1 Real, Reactive, and Apparent Power The real power and energy measurements discussed in the previous section relate to the quantities that are most used in electrical systems. But it is often not sufficient to only measure real power and energy.

  • Page 17: Power Factor

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT So keeping the VAR content low allows a line to carry its full capacity of watts. In order to encourage customers to keep VAR requirements low, most utilities impose a penalty if the VAR content of the load rises above a specified value. 1.3.2 Power Factor A common method of measuring reactive power requirements is power factor.

  • Page 18: Harmonic Distortion

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT Harmonic Distortion Harmonic distortion is primarily the result of high concentrations of non-linear loads. Devices such as computer power supplies, variable speed drives and fluorescent light ballasts make current demands that do not match the sinusoidal waveform of AC electricity.

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT collection of higher frequency waveforms. These higher frequency waveforms are referred to as harmonics. Figure 1.12 shows the content of the harmonic frequencies that make up the distortion portion of the waveform in Figure 1-11. -100 -150 -200...

  • Page 20: Waveform Capture

    CHAPTER 1: THREE-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.

  • Page 21: Power Quality

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT Power Quality Power quality can mean several different things. The terms ‘power quality’ and ‘power quality problem’ have been applied to all types of conditions. A simple definition of ‘power quality problem’ is any voltage, current or frequency deviation that results in mis-operation or failure of customer equipment or systems.
