  • Page 9: Wye Connection

    Grid Solutions EPM 9450/9650 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 10 WYE CONNECTION CHAPTER 1: THREE-PHASE POWER MEASUREMENT Phase 3 Phase 1 Phase 2 Figure 1-1: Three-phase Wye Winding The three voltages are separated by 120 electrically. Under balanced load conditions the currents are also separated by 120 . However, unbalanced loads and other conditions can cause the currents to depart from the ideal 120 separation.

  • Page 11: Delta Connection

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT DELTA CONNECTION Table 1.1: Common Phase Voltages on Wye Services Phase to Ground Voltage Phase to Phase Voltage 7,620 volts 13,200 volts Usually a wye-connected service will have four wires: three wires for the phases and one for the neutral.
  • Page 12 DELTA CONNECTION CHAPTER 1: THREE-PHASE POWER MEASUREMENT Figure 1-4: Phasor Diagram, Three-Phase Voltages and Currents, Delta-Connected 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 13: Blondel's Theorem And Three Phase Measurement

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT BLONDEL’S THEOREM AND THREE PHASE MEASUREMENT Blondel’s Theorem and Three Phase Measurement In 1893 an engineer and mathematician named Andre E. Blondel set forth the first scientific basis for polyphase metering. His theorem states: If energy is supplied to any system of conductors through N wires, the total power in the system is given by the algebraic sum of the readings of N wattmeters so arranged that each of the N wires contains one current coil, the corresponding potential coil being connected between that wire and some common point.

    POWER, ENERGY AND DEMAND CHAPTER 1: THREE-PHASE POWER MEASUREMENT Phase B Phase C Node "n" Phase A Figure 1-6: Three-Phase Wye Load Illustrating Kirchoff’s Law and Blondel’s Theorem Blondel's Theorem is a derivation that results from Kirchoff's Law. Kirchoff's Law states that the sum of the currents into a node is zero.
  • Page 15 CHAPTER 1: THREE-PHASE POWER MEASUREMENT POWER, ENERGY AND DEMAND Typically, electrical energy is measured in units of kilowatt-hours (kWh). A kilowatt- hour represents a constant load of one thousand watts (one kilowatt) for one hour. Stated another way, if the power delivered (instantaneous watts) is measured as 1,000 watts and the load was served for a one hour time interval then the load would have absorbed one kilowatt-hour of energy.

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT REACTIVE ENERGY AND POWER FACTOR Intervals (15 mins.) Figure 1-8: Energy Use and Demand As can be seen from this example, it is important to recognize the relationships between power, energy and demand in order to control loads effectively or to monitor use correctly.
  • Page 18 REACTIVE ENERGY AND POWER FACTOR CHAPTER 1: THREE-PHASE POWER MEASUREMENT Figure 1-9: Voltage and Complex Current The voltage (V) and the total current (I) can be combined to calculate the apparent power or VA. The voltage and the in-phase current (IR) are combined to produce the real power or watts.

  • Page 19: Harmonic Distortion

    CHAPTER 1: THREE-PHASE POWER MEASUREMENT HARMONIC DISTORTION A second type of power factor is Displacement Power Factor. Displacement PF is based on the angular relationship between the voltage and current. Displacement power factor does not consider the magnitudes of voltage, current or power. It is solely based on the phase angle differences.
  • Page 20 HARMONIC DISTORTION CHAPTER 1: THREE-PHASE POWER MEASUREMENT 1500 1000 –500 –1000 –1500 Figure 1-11: Distorted Current Waveform The distortion observed in Figure 1.11 can be modeled as the sum of several sinusoidal waveforms of frequencies that are multiples of the fundamental 60 Hz frequency.
  • Page 21 CHAPTER 1: THREE-PHASE POWER MEASUREMENT HARMONIC DISTORTION Inductive and capacitive impedance are present in all power systems. We are accustomed to thinking about these impedances as they perform at 60 Hz. However, these impedances are subject to frequency variation. XL = jwL and XC = 1/jwC At 60 Hz, w = 377;...

  • Page 22: Power Quality

    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.

An IRIG-B signal-generating device connected to the GPS satellite system synchronizes EPM 9450/9650 meters located at different geographic locations. EPM meters use an un-modulated signal from a satellite-controlled clock (such as the GE MultiSync 1588).
  • Page 77 CHAPTER 5: COMMUNICATION WIRING IRIG-B CONNECTIONS Troubleshooting Tip: The most common source of problems is a reversal of the two wires. If you have a problem, try reversing the wires. IRIG-B Port IRIG-B Time Signal Generating Device Figure 5-12: IRIG-B Communication Please make sure that the selected clock can drive the amount of wired loads.
