Handheld Circuit Breaker Analyzer & Timer CAT-P is a digital instrument for circuit breakers condition assessment. CAT-P records timing graphs of main arcing contacts, DC substation battery voltage, Trip and Close coil currents. Main contacts operating time in on-line mode is calculated based on AC secondary CT’s currents.
Timing is calculated based on AC secondary CT’s currents measured by AC current probes
Number of inputs for current probes: 3
Measuring Range: 0,05 A to 5 ARMS
Accuracy: ±3% ±1 mV (from 0,05 A to 0,5 A),
±1,5% ±1 mV (from 0,5 A to 1 A), ±1% (from1 A to 5 A)
