Handheld Circuit Breaker Analyzer & Timer CAT-P

Product Description
Handheld Circuit Breaker Analyzer & Timer CAT-P is a handheld, battery-operated, fully automatic test instrument for circuit breakers condition assessment. CAT-P is specially designed to capture the “First trip” test and provide an insight into circuit breaker true condition in a real-life fault situation. It 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. The timing channels record closing and opening of the main contacts. Before the start of the test, the current clamp needs to be connected to the auxiliary circuitry of the circuit breaker. The recording starts when the measured coil current reaches predefined threshold. The hooked DC current clamp measures the current through the auxiliary circuit, Trip or Close coil, depending on the initiated operation. CAT-P displays numerical and graphical results (it can overlay up to 4 records in graphical form). This enables quick onsite analysis of potential defects by comparing the obtained test results.
