🎗🎗11KV VCB OPENING &CLOSING TIMING TESTING Testing an 11kV VCB's opening/closing time involves using a Circuit Breaker Analyzer (CBA) to measure contact movement in response to control signals, checking for smooth mechanical action, verifying timing against standards (e.g., 20-40ms for opening, 40-100ms for closing), and ensuring pole-to-pole consistency, all performed after ensuring safety with LOTO and potentially checking vacuum integrity. The procedure focuses on confirming the breaker ope
