What I actually went into the hall for was to look at the phase rotation of the 480VAC for the Left Dipole power supply. The left rotation we found on the Left Q1 Danfysik might have indicated an incorrect rotation for the Left Dipole Dynapower. That might have explained some questions I have. It turns out the 480VAC for the Dynapower on each arm is phased with a left rotation at the power supply, as it needs to be. Well, that doesn't help answer my questions, but that is good. Unfortunately, the wiring of the 480VAC on the power supply platforms is not coded consistently and may date from when the VVUs (Visual Verification Units) were installed. The wiring is switched between right and left rotation in a random fashion. We will need to resolve the 480VAC coding during an extended down.
