Hi, I'm Mike G and I'll be glad to assist you.

Is it one more than one circuit?

Do you have a 2 wire voltage tester?

We can see it now when dryer turned on and lights in kitchen will be effected other night power turned cable box off momentarily
Expert:  Mike G. replied 1 year ago.

More than one circuit puts the problem at the panel or ahead on the utility lines. If lights are brigh and dim it would suggest a bad neutral connection. Open the panel, check the termination of the neutral wire, corrosion on the termination may be present and need to be cleaned and coated with a de-ox compound. If nothing apparent, test the incoming wire terminations. Hot to hot for 240V, each hot to neutral for 120V make the test with the main breaker off. Let me know what you discover.

Checked hot to hot 243v hot to neutral 123v no corrosion visible anywhere in the panel

Is there only the one panel?

Is the surge occurring when you test or not?

Expert:  Mike G. replied 1 year ago.

Test with power on now. The first test was to see if was ahead of the main breaker.

Got it one leg 123v second leg 109v
Expert:  Mike G. replied 1 year ago.

Check connection. Tighten terminations and test again.

Expert:  Mike G. replied 1 year ago.

One more thing. If after tightening the terminations the reading remain the same, pull the breaker and visually check the jaes and the buss for signs of arcing.

Customer: replied 1 year ago.
Retest 126v 114v after tighting 243v across
Expert:  Mike G. replied 1 year ago.

Check the jaws of the breaker for corrosion and or arcing

Customer: replied 1 year ago.
No corrosion pulled several breakers
Expert:  Mike G. replied 1 year ago.

OK, after all that it appears that the issue is on the utility company lines or in the meter. You'll need to put in a troublecall to them. Tell them there is a voltage imbalance and surges.
