  • Page 16: Three-Phase System Configurations

    CHAPTER 2: ELECTRICAL BACKGROUND Three-Phase System Configurations 2.2.1 Description Three-phase power is most commonly used in situations where large amounts of power will be used because it is a more effective way to transmit the power and because it provides a smoother delivery of power to the end load. There are two commonly used connections for three-phase power, a wye connection or a delta connection.
  • Page 17 CHAPTER 2: ELECTRICAL BACKGROUND FIGURE 2–2: Three-Phase Voltage and Current Phasors for Wye Winding The phasor diagram shows the 120° angular separation between the phase voltages. The phase-to-phase voltage in a balanced three-phase wye system is 1.732 times the phase- to-neutral voltage.

  • Page 18: Delta Connection

    CHAPTER 2: ELECTRICAL BACKGROUND 2.2.3 Delta Connection Delta connected services may be fed with either three wires or four wires. In a three-phase delta service the load windings are connected from phase-to-phase rather than from phase-to-ground. The following figure shows the physical load connections for a delta service.

  • Page 19: Blondell's Theorem And Three-Phase Measurement

    CHAPTER 2: ELECTRICAL BACKGROUND Another common delta connection is the four-wire, grounded delta used for lighting loads. In this connection the center point of one winding is grounded. On a 120/240 volt, four- wire, grounded delta service the phase-to-ground voltage would be 120 volts on two phases and 208 volts on the third phase.
  • Page 20 CHAPTER 2: ELECTRICAL BACKGROUND 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, Blondell's Theorem is still applied to obtain proper metering.
  • Page 21 CHAPTER 2: ELECTRICAL BACKGROUND If we measure the currents in wires A, B and C, we then know the current in wire N by Kirchhoff's Law and it is not necessary to measure it. This fact leads us to the conclusion of Blondell's Theorem that we only need to measure the power in three of the four wires if they are connected by a common node.

  • Page 22: Power, Energy, And Demand

    CHAPTER 2: ELECTRICAL BACKGROUND Power, Energy, and Demand 2.3.1 Description 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. 2.3.2 Power Power is an instantaneous reading.
  • Page 23 CHAPTER 2: ELECTRICAL BACKGROUND Time (minutes) FIGURE 2–7: Power Use Over Time The data in the above figure is reproduced in the following table to illustrate the calculation of energy. Since the time increment of the measurement is one minute, and since we specified a constant load over that minute, the power reading can be converted to an equivalent consumed energy reading by multiplying the power reading by 1/60 (converting the time base from minutes to hours).

  • Page 24: Demand

  • Page 25 CHAPTER 2: ELECTRICAL BACKGROUND 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.

  • Page 26: Reactive Energy And Power Factor

    CHAPTER 2: ELECTRICAL BACKGROUND Reactive Energy and Power Factor 2.4.1 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 27: Power Factor

    CHAPTER 2: ELECTRICAL BACKGROUND 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. 2.4.2 Power Factor A common method of measuring reactive power requirements is power factor.

  • Page 28: Harmonic Distortion

    CHAPTER 2: ELECTRICAL BACKGROUND Harmonic Distortion 2.5.1 Harmonics of a Non-Sinusoidal Waveform 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.

  • Page 29: Inductive And Capacitive Impedance

    CHAPTER 2: ELECTRICAL BACKGROUND frequency waveforms. These higher frequency waveforms are referred to as harmonics. The following figure shows the content of the harmonic frequencies that comprise one cycle of the distorted portion of the above waveform. -100 -150 -200 -250 FIGURE 2–12: Harmonics for Distorted Current Waveform The waveforms above provide an indication of the impact of combining multiple harmonic...

  • Page 30: Waveform Capture

    CHAPTER 2: ELECTRICAL BACKGROUND 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 V bus) the user may often see higher order harmonic distortion.

  • Page 31: Power Quality

    CHAPTER 2: ELECTRICAL BACKGROUND Power Quality 2.6.1 Description 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 misoperation or failure of customer equipment or systems.

    CHAPTER 5: COMMUNICATIONS DNP Implementation 5.3.1 Overview The EPM 6000 meter is capable of using RS485 as the physical layer. This is accomplished by connecting a PC to the meter with the RS485 connection on the back face. RS485 provides multi-drop network communication capabilities. Multiple meters may be placed on the same bus, allowing for a master device to communicate with any of the other devices.

  • Page 84: Application Layer

    CHAPTER 5: COMMUNICATIONS 5.3.4 Application Layer The application layer contains a header (request or response header, depending on direction) and data. Application headers contain the application control field and the function code. For the application control field, multiple-fragment messages are not allowed for EPM 6000. Each application header should indicate it is both the first fragment (FIR = 1) as well as the final fragment (FIN = 1).

    CHAPTER 5: COMMUNICATIONS • Change to Modbus RTU Protocol (point 1): EPM 6000 meters are capable of switching from the DNP Protocol to the Modbus RTU Protocol. This enables the user to update the device profile of the meter. This does not change the protocol setting, as a reset returns the meter back to DNP.

    CHAPTER 5: COMMUNICATIONS • Frequency (point 14): This point is formatted as a two's complement fraction. It represents the frequency as measured on phase A voltage in units of cHz (centiHertz, 1/100 Hz). Inputs below 45.00 Hz are pinned at 0 (0000h), while inputs above 75.00 Hz are pinned at 9999 (270Fh).
