The CAT II series circuit breaker analyzers & timers are stand-alone or a PC-controlled digital instruments for circuit breakers condition assessments.
The timing channels record closing and opening of the arcing, resistor and auxiliary contacts. The main contact channels can also measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).
CAT II series records graphs of both, open and close coil currents and displacements of the HV and MV circuit breaker moving parts.
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 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
