Circuit Breaker Analyzer & Timer
Circuit Breaker Analyzer & Timer
Circuit Breaker Analyzer & Timer CAT33 is a standalone or a PC-controlled digital instrument for condition assessment of circuit breakers. The timing channels record closings and openings of main contacts, resistor contacts, and auxiliary contacts. CAT33 records graphs of both Open and Close coil currents and displacements of HV and MV circuit breaker moving parts. Main contact channels can also measure resistance value of pre-insertion resistors (if present in the circuit breaker). Test results are printed on 80 mm thermal printer in tabulated and graphical form.
Product & Technology News
Typical application is:
- Simultaneous measurement of 3 Main contacts and 3 auxiliary contacts, including pre-insertion resistors (if present in the circuit breaker)
- Resistance measurement of pre-insertion resistors (if present in the circuit breaker)
- Evaluation of the synchronization between the circuit breaker poles
- Measurement of coil currents, simultaneously for both coils
- Evaluating the state of the substation’s batteries by graphically showing the voltage value
- Measurement of contact wipe, over-travel, rebound and average velocity of breaker’s moving parts
- “First trip†analyzing method available
- Display and print test results, both numerically and graphically
- Simple & easy to operate
- Timing and motion measurement
- 3 Channels for main contacts
- 3 Channels for auxiliary inputs
