CBA-32P - Micro CBA-32P

The CBA-32P and Micro CBA-32P are portable testing and measuring instruments that rapidly carry out timing tests on circuit breakers of all types that are typically installed in Electric Utility Substations ranging from the lowest voltages up to the highest (800 KV). The CBA-32P is intended for use by Utility Maintenance Personnel in performing periodic maintenance testing on circuit breakers, and start-up tests on new or repaired equipment. It is also in demand from Circuit Breaker Manufacturers for After Sales Product Support. In research and development work, the CBA-32P is renowned for its precision, flexibility, data processing and storage capabilities.

The CBA-32 product line integrates the power of a multi-channel storage oscilloscope with the processing power of a state of the art personal computer. The efficiency with which the CBA-32 carries out tests, and its high-quality graphical display of test results, make it a necessary instrument in all phases of high-voltage breaker maintenance, manufacturing, and development.

The CBA-32 is intended to be connected to a portable computer with color or monochrome screen via a high speed optical fiber link. It is equipped with up to 2 breaker control outputs, up to 24 contact inputs to measure main and resistive contacts in a close or open state, and up to 8 analog inputs for measuring current or linear displacement, pressure, etc.

CBA Win© is a powerful software which integrates all the necessary tools of the high voltage circuit breaker specialist. Designed around the latest improvements in both technical and computer sciences, CBA Win© answers to any user requirements. As a result, it has become the indispensable element of the high voltage Circuit Breaker specialists. It is more than one step ahead of the competition!

The CBA-32D tabletop test instrument, in a standard 19" case, available upon request.

•  3, 8, 16, or 24 optically isolated digital input channels for main or resistive contacts (30-4,000 Ohms depending on the model).
•  2 current analog inputs, each measuring Close or Open coil currents (0-20 A standard). Current sensors are built-in.
•  3 or 6 general analog inputs (0-10VDC) used for linear or rotary displacement measurements. Power for the transducer is supplied by the CBA-32. They may also be used as general purpose analog inputs.

Analog inputs have a resolution of 12 bits each, and are virtually a multichannel storage oscilloscope!

Close and Open commands

•  1 Close coil command output
•  1 Open coil command output

The pulse widths of both these commands is set by the user via a menu selection in CBA Win©. Each output is capable of AC and DC switching. They are DC rated at 500 VDC, 60 A max.; and AC rated at 660 VAC, 60 A max. The breaking current capacity varies inversely with the voltage.
