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 ELITEpro 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
ELITEpro 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.
