The Circuit Breaker Analyzer & Timer CAT124A, CAT125, CAT126 instrument utilizes the latest improvements for safe and fast testing, with unique technical capabilities for additional diagnostics of circuit breakers. Sophisticated design ensures efficient and reliable operations in high-voltage substations and industrial environments.
Features:
4 breaks per phase
Robust design for field use
Accurate measurement in high voltage environment
Timing and motion measurement
Both Sides Grounded feature
Built-in micro ohmmeter (up to 500 A)
Dynamic resistance measurement
Detailed analysis of test results using DV-Win software
12 timing channels (3×4) for main and resistive contacts
6 timing channels for auxiliary inputs
6 coil control channels
3 transducer input channels
6 additional analog input channels
Applications:
Simultaneous timing measurement of up to 12 main contacts (4 breaks per phase) including pre-insertion resistors (if present in the circuit breaker) and 6 auxiliary contacts
Resistance measurement of the pre-insertion resistors (if present in the circuit breaker)
Evaluation of synchronization between the circuit breaker poles
Measurement of the coil currents, voltages and resistance simultaneously for 6 coils
Evaluating the state of substation’s batteries by graphically showing the voltage value
Measurement of displacement, contact wipe, over-travel, rebound, damping time and average velocity of the breaker’s moving parts
“First trip” test
Static resistance measurement
Dynamic resistance measurement
