Sorry, the second line was missed from my earlier reply.
I don't know about voltage, but in maths it is the hypotenuse of a 
right-angled triangle!
I therefore presume it is the measured voltage calculated from knowing 
the active and reactive components of the voltage.

Re: :


Good People 
What is the basis of this formula for working voltage ? 
 sqroot(a^2 + b^2) 
thanks, 
Brian
