Hi Gerry,
The point was that it might be a good idea to ground the coil side
nearest the core. The nearest core to the hv coil is not the core
center, but the outer portion of the E core. Thus, at least in this
case, H2. I think there would have been problems long ago as I doubt
anyone has payed much attention to what's what.
Take care,
Bart

Hi Bart,
OK, I think I understand now. My pig doesnt have this tap switch
unless it is on the inside. Also no mention of it on the diagram.
You say that you suspect the tap connections are on the outer HV
winding??? If this is true, then why ground H2. I thought the
previous discussion was saying that H2 (via the tap switch) goes to
the inner windings of the HV coil that is directly on top of the LV
winding and this is why it is best to ground H2.

Hi Gerry,
The tap is a 5 position switch located on the side of the case
near the top. It switches the HV side. The switch has 1 common and
then switches between 5 positions which are taps at the HV
winding. Here are the tap voltages:
5 = 12540
4 = 12870
3 = 13200
2 = 13800
1 = 14400
Thus, the LV output (in normal distribution use) can be adjusted
as necessary. I of course keep the transformer tapped at position
1. This switch is just below the top
