[Amps] Buck-Boost Transformer Selection

[Glen Zook via Amps]

The power company is not very likely to reduce the voltage!  Especially with the load placed on the distribution systems during the summer months, the company is going to run higher voltage and that means about 127 / 254 VAC.  In this area, Dallas, Texas, area, the line voltage has generally been very near the 127 / 254 VAC levels since the late 1960s during the warmer months.  I don't know about prior to 1967 since I didn't live in the area until April 1967.

The "target" voltage is 125 VAC +/- 2-volts / 250 VAC +/- 4-volts and virtually every electric company runs on the "+" side during the warmer months.

REPLY:

Nevertheless, I would ask the power company to fix it. If they refuse, 
then go from there.
