Data record tests.winding-resistance.ieeec57-12-90.reference-temperature

Verified 2026-10-24 Confidence: High

Clause 5.2 of IEEE C57.12.90-2021 converts a measured winding resistance to the reference temperature with a formula whose material constant differs between copper and aluminum conductors, so the conductor material is part of the record.
