The ultimate all-in-one circuit breaker analyzer: safer, faster, and more accurate than ever. It allows any timing test, motion and speed analysis, multiple contemporary static and dynamic contact resistance measurements, Both Sides Grounded (BSG) tests, under-voltage condition tests, and more. All these functions are integrated into a single lightweight device, without the need of connecting additional external modules.

Characteristics

• Faster: one single connection set up to perform automatically all possible circuit breaker tests
• Safer: both sides grounded feature without any additional external modules
• It performs tests on GIS breakers with both sides grounded (BSG)
• Fully configurable
• 3 micro-ohmmeters (200 A DC output each) performing up to 6 static and dynamic contact resistance measurement
• Three-phase first trip measurement
• 16 or 24 fully user-configurable Main/PIR and auxiliary input contacts
• 2, 4 or 6 Open / Close coil commands
• 3 analog linear/rotary transducers and 3 digital transducers inputs for travel/ speed analysis
• 8 analog input measurements including, battery voltage, motor current, pressure transducers, and many others
• Minimum voltage trip coil test, fully automatic
• On-screen control and test results evaluation
• TDMS software suitable for test executions results in analysis, archiving, and test report
• Library of standard test plans are available with the test set

The CBA 2000is a unique test set for the complete test of all circuit breakers. It is a powerful timing and motion analysis requirement with a built-in 200 A pure DC micro hm meter for static and dynamic contact resistance tests.

The CBA2000 measures CB operation times according to international standards: Open  (O), Close (C), Open-Close (O-C), Close-Open (C-O), Open-Close-Open (O-C-O). It is also possible to set up customized operation sequences.  In this way is possible to get the circuit breaker spread. At the same time, you can measure the coils currents.

CBA 2000 is a stand-alone unit with a large graphical display. The unit is supplied with TDMS analysis software. TDMS performs test results analysis and creates test reports; it allows also to pre-define test plans. TDMS is also a powerful Test and Data Management software compatible with all ISA Test Sets. All CBA 2000circuits have been designed to ensure safe and reliable operations in the noisy environment of EHV and HV substations.

Characteristics

Coil operation

• Number of circuits: 2 (1 Open and 1 Close coil); optional 4 (3 Open and 1 Close coil)
• Type of driver: electronic; it ensures superior timing control
• Driver characteristic: 300 V DC max; 30 A DC max
• Operating time accuracy: 0.025% of delay ± 50 µs
• Measurement of the coil current: one per channel; the waveform is displayed on the dedicated channels
• Coil current ranges: 2.5; 10; 25 A full scale, user selectable
• The 4 coils option allows the selection of single or multiple phase opening
• Coil current measurement accuracy: 0.5% of the reading ± 0.1% of the selected range
• Output is isolated between them
