Data record std.ieee-c37-112.dynamic-conformance

Verified 2026-10-24 Confidence: High

Clause 3.4 of IEEE C37.112-2018 makes dynamic behavior part of conformance: a microprocessor relay conforms only when it implements the integral equation with the trip-equation time rather than a static curve fit, so that coordination with induction relays holds while the current changes.
