Ehv Portable Circuit Breaker Analyzer

EHV Portable Circuit Breaker AnalyzerRoutine tests: time, velocity and stroke1) 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 curve2) Velocity and stroke test-- Open/close instantaneous velocity, max. speed, average speed-- Open-distance, over-travel, bounce-back, total stroke-- "Stroke-time" curve3) Current measurement on closing/opening coils2.2 Reclosing test: close-open, open-close, open-close-open2.3 Low-voltage test: checking out or verifying closing/open coil action voltage.Main technical data of EHV portable circuit breaker analyzerItemDataTime range10ms-15sTime resolution ratio0.1ms; measuring precision +/-0.5% reading +/-0.2msMeasuring precision+/-2% reading +/-0.5ΩMax. speed20m/sMin. stroke resolution ratio0.1mmPowervoltage 20V~250V adjustable, current 20A, digital adjustableDimension410x310x240mmMachine weight10K  We will attend Canton Fair two times each year and also attend overseas specialized exhibition.
