We are going to measure the PF on a three phase 220vac power supply panel. The power supply is 3 hot phase(RST) , one neutral phase and one Ground. Hot phase to hot phase using an Clampon ampmeter is 220vac, Hot phase to neatral is 127vac, Hot phase to ground is 127 vac/50hz.
There are only two leads from the clamp on meter. So when I put the clamp on amp meter say on phase R, where do I then correctly put the two Probes of the Clampon amp meter which also can let mee see the PF? Where to connect for all theree phases? I get conflicting readings measuring the PF putting the two probes between any of the three HOT phasesm and between any hot and the neutral?
Pls assist with this.
