101
If there are no harmonics present, the displacement power factor and harmonic power factor are
identical. If harmonics are present, the harmonic power factor (3 element) will always be smaller than
the displacement 100 power factor (2-element). Similarly, the 3-element VA will always be larger than
the 2-element VA. When comparing the
ELITE
pro
XC
three-phase measurements with other meters,
make sure that the same method of calculating VA and Power Factor is used.
Connecting the ELITEpro XC to a 3-phase 3-wire Delta load using the 3 element method:
It is very similar to the 3-phase, 4-wire WYE connection. Use a CT on each phase and connect the three
ELITE
pro
XC
voltage wires to each phase. The neutral wire should then be connected to earth ground.
The Setup table should look just like that of the 4-wire WYE setup. See
ELOG Quick Setup Wiring
Diagrams
in Section II.
