Data record std.ieee-c57-12-90.test-order

Verified 2026-10-24 Confidence: High

A note in clause 4.3 of IEEE C57.12.90-2021 recommends that the dielectric tests come after the tests made at reduced voltage: winding resistance, polarity with phase relation, turns ratio, no-load loss with excitation current, impedance with load loss, and temperature rise.
