Verified 2026-10-24 Confidence: Medium

Clauses 10.7 and 10.8 of IEEE C57.12.90-2021 perform the induced-voltage test by exciting the transformer at a raised frequency so that the core does not saturate, for a duration stated in cycles or time, with the Class II procedure adding an enhancement level followed by a lower level held for an extended period during which partial discharge is read at intervals and judged against the magnitude, rise and trend criteria of clause 10.8.5.
