Circuit Breaker Analyzers & Timers
CAT Advanced Series
-
DV Power circuit breaker analyzer and timer utilizes the latest technological enhancements for safe and fast testing of circuit breakers. The sophisticated design ensures efficient and reliable operations in high-voltage substations and industrial environments.The CAT Advanced series are stand-alone or PC-controlled digital instruments for a circuit breaker testing. The timing channels record closing and an opening of the arcing, resistor, and auxiliary contacts. Also, the main contact channels can measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).With CAT Advanced series instruments, it is possible to record graphs of open and close coil currents. Furthermore, it records displacements of the HV and MV circuit breaker moving parts. Test results can be saved via USB, PC or be printed via 112 mm (4.4 inches) thermal printer (optional accessory) in tabular and graphical form.A circuit breaker test consists of different operational modes and CAT Advanced series supports:Open (O)Close (C)Reclose (O-0,3s-C)Trip free (CO)O-0,3s-COOpen-Close (O-C)Close-Open (C-O)Open-Close-Open (O-C-O)First trip (O)Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by sensing a breaker’s contact position.The auxiliary inputs are used to monitor dry and wet auxiliary contacts. The six coil control analog channels measure and record coil currents simultaneously (OPEN and CLOSE), up to 35 A AC/DC.The additional six voltage analog channels have four selectable voltage ranges available (±1 V, ±5 V, ±60 V and ±300 V AC/DC).A built-in micro-ohmmeter generates up to 500A true DC ripple-free current with an automatically regulated test ramp that provides performing static and dynamic contact resistance measurement.Three transducer channels provide a measuring displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time and average velocity. Also, a user can connect either an analog or a digital transducer to these universal channels.
