Hey Ken & Grumpy
I started a new thread from the 7.5 VAC xfmr, because the subject has
drifted. You guys mentioned a DC component in pole pigs. Sometime ago
I heard that if an AC circuit had too many switching power supplies on
it, that would cause the power company all kinds of problems. What were
or are the problems and what was the evidence and what did the power
companies do to solve the problem?
