Voltage Monitoring Channels
The CT-8000 S3 features three voltage monitoring input channels (V1, V2, and V3). The V1
voltage channel is dedicated to monitoring the substation DC supply or coil voltage (0-255 V, DC
or peak AC). The nominal and minimum DC supply voltage levels are recorded and printed on
the tabulated report. An analog waveform showing the DC power supply is plotted on the
graphical report. The two digital voltage input channels, V2 and V3, are dedicated to monitoring
voltage on/off status presence or absence of the circuit breaker auxiliary switches. Digital
waveforms showing V2 and V3 activity are plotted on the graphical report. Three timing events
of the V2 and V3 activities are recorded and printed on the tabulated report.
Breaker Initiate Features
A built-in solid-state initiate device is used to operate a breaker from the CT-8000 S3.
Operational modes include OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN.
Multiple operation like OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN can be initiated by
using a programmable delay time (in milliseconds) or by sensing a specific breaker contact
condition.
OPEN/CLOSE Coil Current Monitoring
One built-in, hall-effect sensor records the OPEN/CLOSE coil current amplitude and waveform.
The circuit breaker’s coil current waveform, effectively, a coil performance “fingerprint” or
“current profile”, can be used as a diagnostic tool for analyzing the circuit breaker’s
performance.
Computer Interface
The CT-8000 S3 can be computer-controlled via the USB or optional Bluetooth interface.
Windows-based Circuit Breaker Analysis Software is provided with each unit. Using this
software, circuit breakers can be timed from the PC. Test records can be retrieved from the CT-
8000 S3 and then stored on the PC for future analysis and report generation. Circuit breaker
test plans can also be created on the PC and transferred to the CT-8000 S3. Additionally, test
records can be automatically exported in Excel, PDF, and XML formats.
Built-in Thermal Printer
The CT-8000 S3's built-in 4.5" wide thermal printer can print the breaker contact analysis
results in both tabular and graphic formats.
User Interface
The CT-8000 S3 features a back-lit graphic LCD screen (240 x 128 pixels) that is viewable in
direct sunlight and low-light levels. A rugged 44-key "QWERTY"-style membrane keypad is used
to control the unit and input information.
