Data record instr.transformer-turns-ratio-tester.readout

Verified 2026-10-27 Confidence: High

The tester reports three quantities for each measurement: the measured ratio, the excitation current, and the phase deviation between the applied and the induced voltage; given the nameplate voltages it also computes the percentage deviation of the measured ratio from the expected ratio.
