I receive 100amp service to my home. My power conditioner NEVER stays at a constant voltage. It varies between 122.1 - 124.4 The home was built in the 1950 with original service to home. (3 individual power cables coming from the pole to the home). It should read 120 correct?
Before using a power conditioner I received a ground feedback hum (coming from the cable t.v.) still happened even after installing a cable tv ground from local electronic store. $5.00. The power conditioner filtered out the noise. I don't understand why the voltage changes constantly. throughout the day it reads a different voltage.
Power Conditioner is Monster 2550.
f.y.i. The house is mixed with both grounded and ungrounded outlets. Only the kitchen and bathroom were grounded. There are grounded outlets in the home, but they are not really grounded (reading a hot/neutral reverse via outlet tester). Not sure if this is causing problems. Electrician will be arriving in 2 weeks to hookup hot tub. Anything I should have him check while he's here?

The voltage range you're seeing is perfectly normal and within the utility company's tolerance. Voltage does not remain at a rock solid 120V but fluctuates constantly throughout the day as your neighbors and other users of electric power in your area turn their devices on and off. Wait until summer comes around and all the air conditioners go into use. Voltage is likely to drop a good bit below the 122V lower limit you're now seeing.
