114 to 126 is typically the standard in the USA. Many transformers have taps 
internally to adjust for this, but some utilities order them without taps to 
save a few bucks.

  Subject: Re: [Repeater-Builder] OT Power Factor


  Very interesting subject.  People don't seem to be concerned about what kind 
of energy they are receiving from electric power company suppliers.  I've asked 
previously for information about what people get in their homes and repeater 
sites with only one response telling me taps are available to solve a high or 
low problem.  Do phase shift capacitors have an effect on our home our test 
equipment, repeaters? The AC specs here are 115.2 - 124.8. A calibrated NBS 
Fluke 77 reads consistently on the high end, and frequently up as high as 128.  
The power company engineer says they can do nothing about it, that taps do not 
exist anywhere in the system  to lower the line voltage. Only phase shift 
capacitors. Our older test equipment designed around a 115 volt line plus AC 
motors, power transformers can have a problem with saturation.  On a room to 
room/ garage/ shop investigation how many transformers, motors are in your 
dweling? Those big honker 30 amp or higher power supplies on repeaters going up 
in smoke. What's in your wallet....I mean your electric service line?
