Kennyvp,
A few things need to be addressed first off, as follows:
<OL TYPE=A>
[*] What is the intensity of the dimming problem,
[*] How long does the dimming last,
[*] Is the dimming predictable and constant during various times &/or days of the week,
[*] Does the dimming occur in one general area of the Homes, or on a certain circuit only,
[*] Does the dimming occur most noticably with Incandescent Lamps,
[*] Does the "opposite" ever occur frequently
</OL>
As to "A", does the light level dim very drammatically, gradually taper down, or just come and go very transiently?
For "B", does the dimming last for several seconds, vary in time per type of load starting, or is the dimming more like a "Flash"?
Per "C", can you intentionly start some hard starting load and get consistant dimming results at all affected locations, and will this be the same every day - regardless of the time of day?
As to "D", is the dimming confined to "Certain Areas" of the House(s)?
For "E", Incandescent Lamps + Humans' perceptions of light levels are - to say the least -
"greatly emphasised by minute changes", meaning small changes in Voltage cause Incandescent Lamps to react drammatically - and the Eyes also react drammatically.
Fluorescents will dip slightly, but normally are unnoticed when Transient Voltage sags come along. Flicker is more noticed.
As to "F", do any Incandescent Lamps tend to get brighter when Motors start?
