    In a wye service the neutral (or center point of the wye) is typically grounded. This leads to common voltages of 208/ 120 and 480/277 (where the first number represents the phase-to-phase voltage and the second number represents the phase-to-ground voltage).

  • Page 22: 2: Delta Connection

    In many delta services, one corner of the delta is grounded. This means the phase to ground voltage will be zero for one phase and will be full phase-to-phase voltage for the other two phases. This is done for protective purposes. Electro Industries/GaugeTech ™ Doc# E151701 Powered by Innovation™...

  • Page 24: 3: Blondell's Theorem And Three Phase Measurement

    The 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. Electro Industries/GaugeTech ™ Doc# E151701 Powered by Innovation™...
  • Page 25 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.
