EHV Portable Circuit Breaker Analyzer
Routine tests: time, velocity and stroke
1) Time test
-- Closing/opening time
-- Simultaneity in-phase (time difference between contacts in same phase)
-- Simultaneity between-phase
-- Bouncing frequency and time
-- Contact closing/opening-time curve
2) Velocity and stroke test
-- Open/close instantaneous velocity, max. speed, average speed
-- Open-distance, over-travel, bounce-back, total stroke
-- "Stroke-time" curve
3) Current measurement on closing/opening coils
2.2 Reclosing test: close-open, open-close, open-close-open
2.3 Low-voltage test: checking out or verifying closing/open coil action voltage.
