If you're in the US, then the utility voltage will vary anywhere between 114 and 126 Volts - which is normal and the allowable US standard. Appliances with UL listings will operate between 110 and 127 volts with no damage. Also, utility voltage is RMS, meaning it's an average of sorts. The actual voltage at your outlets can be much higher - the peak to peak voltage can reach 170 volts. Your fluke meter is most likely not a true RMS meter and therefore not giving you an accurate measurment with respect to the average or RMS reading. You can call the utility and tell them you suspect high voltage and are concerned and let them make the call. If it was my house, I wouldn't worry.
