Data record instr.surge-tester.waveform-comparison

Verified 2026-10-27 Confidence: Medium

In the surge comparison test the oscillation recorded from each phase is overlaid on the others or on a reference from a known good winding; a weak turn insulation that arcs under the pulse shifts the waveform, and built-in software assists the comparison.
