Easy to Use, Available in 3, 6, or 12 Dry-Contact InputsThe Model CT-6500 Series 2 is a stand-alone, microcomputer-driven EHV Circuit-Breaker Analyzer. It is inexpensive and easy to use. The CT-6500 is available inmodels with either 3 dry contacts (CT-6500-3); 6 dry-contacts (CT-6500-6); or 12dry-contact inputs (CT-6500-12). The CT-6500 fully analyzes circuit-breaker per-formance: contact time, stroke, velocity, over-travel, and contact wipe. Contact-motion analysis includes: Open, Close, Open-Close, Close-Open, and Open-Close-Open. The CT-6500 timing window is selectable: 1-second, 10-second, or 20-sec-ond periods. The 10 and 20-second timing windows allow timing the long durationevents (Circuit-Switcher contacts).

Contact Timing InputsBreaker contact timing uses dry-contact input channels. Each contact-input chan-nel can detect main contact and insertion-resistor contact times (milliseconds andcycles).

Voltage Monitoring InputsOne analog voltage input channel is dedicated to monitoring circuit-breaker dcpower supply or coil voltages 0 to 300 volts, dc or peak ac. One digital voltageinput channel allows users to monitor voltage on/off status of an A/B switch.

Trip/Close Current MonitoringA built-in Hall-effect current sensor records Trip/Close current level and duration.The breaker’s operate-coil current waveform duration (effectively, a performance"fingerprint" or "current profile") can be used as a diagnostic tool for analysis ofa breaker’s performance.

Breaker Stroke and VelocityThree travel transducer digital channels let the CT-6500 measure stroke, over-trav-el, and bounce-back. Unlike other types of transducers, the digital transducerrequires neither calibration nor setup.

Slow-Close TestWhen a cable-connected travel transducer is attached to a circuit breaker (formeasuring contact velocity), the Analyzer can also print out a table of "slow-close" test results. This Analyzer’s feature is a tool for accurately measuring con-tact-travel during circuit-breaker maintenance (when the circuit-breaker con-tact motion is slowly jacked through the stroke by manual operation i.e., ahand-operated "slow-close" test).

Timing Record Storage CapabilitiesThe CT-6500 uses Electrically Erasable PROMs (EEPROMs) to store timing-records data. Unlike other storage media, EEPROMs are immune to shock, tem-perature, and humidity. Stored timing records can be recalled by users to re-analyze test data, to print copies, or to transfer data to an IBM-compatible PCfor record keeping. Up to 200 timing records can be stored in EEPROMs.

Breaker Initiate FeaturesA built-in solid-state initiate device lets users operate the breaker from the CT-6500. The operational modes include: Open, Close, Open-Close, Close-Open,and Open-Close-Open. Multiple operations (e.g., Open-Close, Open-Close-Open) can be initiated by using programmable delay time or by sensing break-er’s contact condition.

Diagnostic CapabilitiesThe CT-6500 can perform diagnostics on its internal electronics. Self testing oftransducer and contact-test cables lets users check out the Timer whenever ver-ification is required.

Computer InterfaceThe CT-6500 can be used in the stand-alone mode or computer controlledmode. USB and RS-232C Ports allow an IBM-PC compatible computer to con-trol the CT-6500. From the PC, circuit breakers can be timed and users canretrieve timing shots saved in the CT-7500 flash EEPROM. A Windows® XP-basedBreaker-Analysis software lets users time circuit breakers, retrieve test-shotdata stored in the computer’s hard-drive, re-analyze the stored data, and gener-ate reports in the office. Test reports can be exported to Excel, allowing the userto generate customized test-result reports. Users may also create a circuit-breaker database library.

User InterfaceAn alpha-numeric keypad lets users enter breaker ID and control functions. A 4-line by 20-character LCD readout displays user messages. The LCD is back lightedso messages can be viewed in low light levels. A display contrast control is locatedon the front panel.

Built-in Thermal PrinterA built-in thermal printer prints the breaker contact analysis results in both tabu-lar and graphic formats on 4.5-inch-wide thermal paper.
