The CBS monitors interrupter wear, integrity of the SF6 gas system, the circuit breaker mechanical system, the electrical control system and auxiliaries. It consists of a modular microprocessor unit and sensors. The CBS is readily available to be applied on all ABB dead-tank breakers. Upon request, installation kits can be provided for ABB GIS and live-tank breakers as well. The current firmware version is 3.60. CBS Lite™ The CBS Lite is intended to be used in applications requiring high-end monitoring capabilities in a cost-effective package. The CBS Lite provides the same functionality as the regular CBS, with the exception that contact travel is simulated, not measured. The CBS Lite is offered for installation on both ABB and non-ABB single-pressure SF6 circuit breakers. The current firmware version is 3.58. CBS Lite CSA™ The CBS Lite CSA is a variant of the CBS Lite. As with the Lite, the CBS Lite CSA can be installed in both ABB and non-ABB single pressure SF6 circuit breakers. The difference between the two products is the replacement of heater monitoring with 3 coil signature analysis inputs. The current firmware version is 3.57. CBS-F6® The CBS-F6 gas monitor is intended to be used in applications not requiring the full monitoring capability of the existing CBS or CBS Lite. It provides the same algorithms that are used in the CBS device today, but strictly monitors gas pressure, temperature and temperature compensated pressure. The CBS-F6 can be applied to any SF6 filled switchgear, both ABB and non-ABB. The current firmware version is 3.53.
