I'm the last customer on a rural electric line. I have a voltage that fluctuates (no surpirse) but is typically in the 245 range and has spiked to 252 (per the ONCOR electric folks). He claims meter data shows highest voltage every 15 minutes... But I caught him in a few fudging lies. He claims that they have a target voltage of 240V and can deviate as much as 10%. In other words, 216 to 264. To which I call BS. On individual legs I've seen 127V in one instance. Obviously, I see LED bulb lifespans of 3 months or so, incandesants 6 months, and CFLs maybe 6 months. I'm getting pretty annoyed... My normal average load is 4-8 kW. So, any ideas that are affordable and will help? I'm obviously not going to get any from ONCOR. Anyone have a link to power standards that I can read up on? Thanks in advance....
