Hi, Darrel
May be you could find a turnaround ...
if you found an info, on motor id. plates ; a number like "cos xx = .85"
Generally it's written there. May be also in the motors datas ...
your intensity will be
SQR ( ( I1_meas. * sin xx1 + I2_meas. * sin xx2 )^2 + ( I1_meas. * cos xx1 + I2_meas. * cos xx2 )^2 )
with I1_meas, xx1 related to motor 1 and I2, xx2 to motor 2.
this could seriously simplify things ... don't you think ???

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Got me all excited with that one Alain.Originally Posted by Acetronics
Made a spreadsheet, was playing with the numbers, kinda almost could see how it might work.
Went to find the cos = .xx ...
Oh no! Don't have that info.

For an inductive circuit like this, it's the Power Factor. However, for more complex non-linear circuits it gets more complicated.

Hi, Darrel
You've one left chance ... on the motor itself, there's a metal little sheet where it MIGHT be written. ( a summary of the main characteristics ... including this COSxx )
Alain
HEYYYYYYYYYYYYYYYYYYYYYY ..
POWER FACTOR = 66 ...% on 17th line !!! .... means Cos xx = .66 and Sin xx = .75
You had it under the eyes !!!

fooling utility meter
the only way to make a utility meter to run backwords is to supply power back out to them.
a pure capacative load will draw amps at 90' but not turn meter.
