I have resently submitted a post on this but I have more information for review. Stated in my resent post we had a contractor read our power factor on each phase. he claims that the power factor in phase A is 50% phase B is 98% and phase C is 80%.
The meter he used is a Fluke 43B.
The incoming power from our main switchgear is 480 volt 2000amp 3phase wye connection.
The contractor insists we reinstall this meter. I was given directions on how to install the meter. Install current probe on phase A. No mention on direction of current arrow on current probe.install voltage probes on phase B and one on Phase C.
Question will that give us the correct power factor on Phase A?
How do you get the power factor readings on the other phases? Do you need to move the voltage probes in respect to the CT?
What i really need to know is this meter able to read the power factor in a three phase wye connection accuratly?
I realize a three phase quality analizer would do the task but i need to prove to "management" this is the incorrect meter to do the job.
