Voltage Requirements
The Operating Voltage from one transformer's high side must match the next transformer's low side.
In the example below, the step transformer at the far left (in red) has a high side voltage (operating voltage) of 12.5kV and a low side voltage of 7.2kV. The step transformer's high side voltage matches the operating voltage of the upstream primary and the step transformer's low side voltage matches the operating voltage of the downstream primary (7.2kV).
