I have had problems with lights dimming. I have had post on here before about it, but unfortunately still not found problem. I have had some new test, and info. So I thought I would try everyone again. I am still stumped.
1. I have tested all connections in panelboard.
2. I have checked to see if load is balanced.
3. I have had Power Company check all connections on their end.
4. I have done voltage test to see if it is ok (my multimeter does not pick up any real VD.
5. Lights will dim when load is on 15A circuit I.E.(hair dryer, sweeper)
6. I have had logging meter check for voltage spikes or dips (no major ones). Plus light do not dim unless load on.
Now with help of my new circuit analyzer, I have found out that all though my multimeter did not pick it up my circuit analyzer shows an 8.7%VD on one outlet and a 15.4% on another. Now maybe its 14AWG wire, or maybe loose connections on devices them selves. The thing is I have a very low neutral to ground resistance. This should mean I have both good grounding wire connection, and a good neutral wire connection. This would again lead me to the hot wire, but what are the odds of both lighting circuits having loose hot some where?
This got me thinking about grounding rod again, if bad ground then it would explain lightning strike I get affecting my electrical system. The circuit analyzer would only test resistance from grounded wire to grounding wire in my house; not to the ?earth ground?. So I could still have bad ground resistance and not now it. The power company says it is fine (of course). I am still convinced this is problem. So I am going to a new grounding system.
The question is if any of you see this, and find a different reason, or opinion. Then I would love the input.
