IBEKO Power AB
CAT circuit breaker analyzers and timers are advanced standalone or a PC controlled instruments for circuit breaker maintenance. Typical application areas of CAT instruments are medium and high voltage substations at electric power generation, transmission, and factories of switchgear. Also, industrial environments and electric power distribution are suitable application areas for these circuit breaker testing instruments.DV Power CAT circuit breaker testing instruments are portable and lightweight. They are designed for performing mechanical operations intended for circuit breakers testing according to standards IEC 62271-100 and IEEE C37.09.These instruments measure:the timing of main contacts, pre-insertion resistor contacts, auxiliary contacts operations,coil currents,motion parameters,voltage recording,main circuit resistance,arcing contacts wipe,and any relevant analog signal.Motion transducer channels provide measuring a displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time, and average velocity. Even more, CAT circuit breaker analyzer optionally has a built-in micro-ohmmeter. Hence, it provides the main circuit resistance measurement and dynamic resistance measurement. Dynamic resistance measurement is an effective method for arcing contacts condition assessment.

CT-8000 S3 -
Manta Test Systems
The CT-8000 S3 is Vanguard’s fourth generation EHV circuit breaker analyzer. The CT-8000 S3 is available with 3 (part number 9103-UC) or 6 contact timing channels (part number 9104-UC). The CT-8000 S3 can fully analyze a circuit breaker’s performance by measuring the main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes. Also, an outstanding feature of the CT-8000 S3 is the ability to perform dynamic resistance tests on circuit breaker contacts.
