Circuit Breaker Analyzer app simplifies vibration analysis, preventive maintenance

February 19, 2013 | By Anthony Capkun

February 19, 2013 – Circuit Breaker Analyzer claims it has introduced the world’s first app for iPhone capable of capturing vibration signatures from working circuit breakers to provide quantifiable data for computerized maintenance management systems (CMMS) and other preventive maintenance programs. Using the accelerometer inside every iPhone or new model iPod, the app captures vibration data in all three axes, as well as across time, at sample rates of 100Hz to 400Hz, depending on the version. Both sample rates provide ample data, says the company, for a detailed vibration signature for later analysis of potential mechanical faults inside the circuit breaker. By comparing the newly acquired vibration signature to a database of known good profiles, and/or the vibration signature of the breaker’s ‘first trip’ operation, pattern recognition algorithms can determine when changes in the ‘envelope’ or shape of the vibration signature indicate a hidden mechanical problem.
