Ok lets discuss what a var is and what it does
60 cycles per second. That's "unity". AC = alternating current. It flows back and forth 60 times in one second.
If a generation or consuption unit is out of unity it will affect the connected system accordingly.
It cant be explained as 59 cycles, or 61 cycles because, engineers.
A "scale" from low to high follows. 1 being unity.
-.95, -.96, -.97, -.98, -.99, 1, +.99, +.98, +.97, +.96, +.95
- is a "leading" power factor.
+ is a "lagging" power factor
Again, "1" is "unity" which =60 cycles per second.
Resistive load (incandescent bulb, toaster, electric cook top) will maintain unity, as supplied by the grid.
Inductive load (fans, motors, fluorescent lights) will alter the power factor. Either leading or lagging.
Variable speed motors will really wreak havock on the cycles per second.
These are measured in VARS, or more correctly for generation and transmission, kVARS. (thosands of VARS)
Remember, leading power factor is - (minus) and lagging power factor is + (plus).
