When the firing cables are connected to the thyristors in the power
unit, the line and armature voltages are automatically present at the
firing pulse transformer module.
These voltages can then be routed from here (connections X12_1,
etc.) to the voltage measurement equipment, without having to route
any additional cables to the power unit.
