Data record instr.circuit-breaker-analyzer.opening-velocity

Verified 2026-10-27 Confidence: High

The opening velocity is the most critical travel parameter because the interrupter has to move at its design speed to build up the stream of air, oil or gas that cools the arc enough for the current to be interrupted at the following current zero; the analyzer calculates velocity between two points chosen on the motion curve, most commonly referenced to contact separation.
