Actually, by adjusting the primary tap up, to match the higher input voltage, it also affects the secondary voltage by bringing it down to a more desirable voltage.

That all depends on the specs and tolerances of the appliance....

yeah thats correct. the transformers used for split phase service usually dont have secondary taps to adjust the output voltage. its a fixed turns ratio....
and a regulator is something entirely different, though it does have a transformer.... step-down transformers on poles or pads, for services, would never be regulators... that would be too expensive to deploy
transformers for 3 phase banks will often have secondary taps which allow adjustment of output voltage... but thats still not the same as a voltage regulator which auto adjusts its voltage output depending on voltage input...
The 14KV distribution line that feeds your transformer would have a voltage regulator on it at some point on the line....
yup that would be done with a voltage regulator....
thoughts?
you need to get logs of these voltage spikes. Or see if they have a logging meter they can put on your service so they can see whats going on before the tech gets to your house...i definitely wouldnt adjust your inverter... 264v and even 255V is too hot for my PoCo's standards (5%)

If you play that game, it helps to know who sits on the commission and how they got there. Knowledge is power (no pun).To the OP. Get in touch with the PoCo and tell them you would like to have them meet with you and the Public Utilities Commission of Texas. Generally speaking, the threat of getting the commission involved is enough to get them moving.
