[GreenKeys] Measurement of Power Line Noise

[John Spigel]

To get the same energy delivered to the customer at a power factor less 
than 1 you need more current. More current means more watts lost in the 
lines, xfmrs, etc in the distribution. The utility eats a lot of these 
losses and may need to invest in more generation, power purchase, larger 
lines and transformers.  Your large commercial and industrial  customers 
have a line item for demand load in KW and another for PF, power factor, 
on their monthly bills in addition to the KWh we see on our bills. A 
simple example for a power factor of .95, the power company is providing 
100W and billing you for 95W. For large industrial campuses you can 
automate the correction to keep current and voltage in phase, make the 
utility happy and get a good return on the investment.
