We have one Energy meter for Measuring the
voltage,current,power,energy(KWH,KVARH,KVAH) & power
factor.The problem is that the meter does not show whether
the PF is lagging or leading.So i want to know that is
there any way or calculation to find out that whether the
PF sign (lagging or leading) depending upon the above
mentioned parameters?

Answer / john
Is this a revenue meter from the utility company or a power
quality meter? In the case of a power quality meter, there
should be something letting you know if your PF is in a lead
or lagging. I have an Amprobe DMII Pro and it showes an i
after the PF to indicate lagging, .98i, and a c to indicate
leading, .98c. I have also seen meters with lagging PF -0.98
and leading +0.98. Another simple thing you can do is look
at your VAR, if it is in the negative, your in a lead.
As far as a revenue meter from the utility company is
concerned, call the utility company and ask them.

How much Fault current can be contributed by a motor?
We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
