Three-phase delta load

7 parts

A delta source drives three 100 Ω resistors connected corner-to-corner — no neutral wire exists, three lines carry everything. The differential probes read the line-to-line voltages: 10 V peak each, with zero-crossings measuring exactly 120.0° apart even though only two of the source's internal branches are stamped — the third line is emergent, and the three voltages still sum to zero at every instant (measured below 2 fV). A 3 × 100 kΩ artificial-neutral wye grounds the otherwise-floating delta at its star, drawing a negligible 58 µA against the loads' 100 mA.
