Power Factor Correction weirdness?
Can someone explain what I'm seeing when I attempt to power factor correct
my neons? I've got my DMM in series with the primary of a 12,000 60mA NST,
and the secondary of the NST is shorted. With no PFC caps, it reads 7.13
Amps. But when I start adding caps in parallel with the NST primary, the
current reading drops dramatically-- more than I expected it to. Here are
PFC Caps Ammeter Reading (amps)
50 uF 4.96
100 uF 2.81
150 uF 1.14
What's going on here? is this right?
