Data record `tests.leakage-reactance.ieeec57-12-90.factors`

Verified 2026-10-24 Confidence: High

Clause 9.2 of IEEE C57.12.90-2021 notes that the tap position changes both the load losses and the impedance, that a rise in temperature raises the resistive loss and lowers the stray loss, and that, because the test runs at a low power factor, a phase-angle error in the metering instruments materially affects the measured loss.
