Circuit Breaker Analyzer & Timer CAT61/CAT64 is a standalone or a PC-controlled digital instrument for condition assessment of the circuit breakers. It is intended for testing timing and travel on circuit breakers with two breaks per phase.
The timing channels records closing and opening of the main, resistor, and auxiliary contacts.
CAT61/CAT64 record graphs of both the open and close coil currents and displacements of the HV and MV circuit breaker moving parts.
Features:
2 breaks per phase
6 timing channels for main and resistive contacts
3 timing channels for auxiliary inputs
TRIP & CLOSE coils current measurement
Resistance measurement of pre-insertion resistors
4 Analog Inputs + 1 Transducer Input
Supports both digital and analog transducers
Timing and motion measurement
Voltage and current measurement
Simple and easy to operate
Robust design for field use
Accurate measurement in high voltage environment
Detailed analysis of test results using DV-Win software
Application:
Simultaneous timing measurement of up to 6 main contacts (2 breaks per phase) including preinsertion resistors (if present in the circuit breaker) and 3 auxiliary contacts,
Resistance measurement of the pre-insertion resistors (if present in the circuit breaker),
Evaluation of synchronization between the circuit breaker poles,
A measurement of the coil currents, simultaneously for 2 coils,
Evaluating the state of the substation’s batteries by graphically showing the voltage value,
A measurement of displacement, contact wipe, over-travel, rebound, damping time and average velocity of the breaker’s moving parts,
“First trip” test.
