HV Circuit Breaker Vibration Analyzer - CBV-27

The new CBV-27 is a high performance, software driven data acquisition system, operating under Microsoft Windows.

The CBV-27 is designed to perform timing & motion analysis on all types of circuit breakers typically installed in electrical substations going from the distribution level all the way to high voltage levels, up to 800 kV. The timing and motion analysis is done based on the International Standard CEI56.

Furthermore, the CBV-27 also comes with the capability to record vibro-acoustic signals having rich frequency content. It allows the detection of the different mechanical faults in all types of circuit breakers.

OpenZen is a highly integrated and specialized software environment that includes all the necessary tools for testing in the field or in the laboratory, for processing, calculations, analysis, interpretations of test results and online help needed by circuit breakers maintenance professionals OpenZen is included with the system free of charge with unlimited updates.
