CAT250 series inherited all capabilities and experience collected from market leading CAT Advanced series.
CAT250 introduces unique touch screen interface designed to significantly save the time required for test preparation and results analysis of all types of medium- and high voltage circuit breakers.
Test results could also be printed on the 112 mm (4.4“) thermal printer (optional accessory) in tabular and graphical form.
The CAT250 series circuit breaker analyzers & timers can be coupled with DV Power Coil Analyzer SAT II series to create one test system (control and testing done with CAT250 touch screen interface) capable to perform the following list of applications:
Built-in micro-ohmmeter (optional) provides high current for dynamic and static resistance measurement, as well for BSG timing measurement of dead tank circuit breakers.
The additional six voltage analog channels have four selectable voltage ranges available (±1 V, ±5 V, ±60 V and ±300 V AC/DC). They are used to monitor:
Three vibration channel inputs record circuit breaker vibration fingerprints providing non-invasive assessment of the circuit breaker main contacts using vibration-based analysis.
Three transducer channels provide measuring displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time and an average velocity. Either an analog or a digital transducer can be connected to these universal channels.
Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form.
