You need a delta load(phase to phase) to get 4160. I simulate loads at 1 ohm to make the amperage match the voltage

This 1 ohm resistor will tell me the voltage between two phases

Using a high ohm load between two phases will introduce the least burden and show you the line voltage between phases, which is 4160.

You understand the delta load? Otherwise your waveforms show 2400 volts and not 4160 volts phase to phase. except for the 1 giga ohm resistor which shows single phase voltage even though it is phase to phase voltage, look at the voltmeter waveform is one wave.

But I don't think the burden is a concern when you are dealing with grid voltages, unless all you are trying to do is measure the voltage. In which case you don't even need burden resistors, a high voltage voltmeter will tell you the voltages phase to neutral or ground, and phase to phase. But if there is a concern about the burden imposed on the system, it is fine to use that high resistance resistor.

So there isn't there isn't a difference of 4160 volts from phase to phase in this system? You understand line voltage, regardless of load? The "high ohm load" IS the physical representation of a voltmeter is this case. I don't see why you're insisting on delta loads. Any load requiring two phases of a three phase wye will have 1.732xphase voltage applied between those two terminals. Where's the disconnect?

This is only meant to show a wye configured generator with output of 2400/4160VAC
