1. A vibration analysis system for performing vibration analysis of operation of a circuit breaker to analyze a mechanical condition of the circuit breaker, the vibration analysis system comprising:

  • an analyzer comprising;

    an accelerometer operable to measure forces of mechanical vibrations along at least two axes that are generated adjacent a surface of the circuit breaker during an operational event of the circuit breaker;

    a magnet operable to couple the accelerometer at a position to measure the forces of the mechanical vibrations that are generated adjacent the surface of the circuit breaker during the operational event of the circuit breaker;

    a leveling system using a gyroscope to determine orientation of the analyzer along least one axis;

    a first memory comprising;

    a storage configured to receive and store a measured mechanical vibration signature of an operational event of the circuit breaker to be analyzed;

    a second memory comprising;

    a database configured to receive and store a known mechanical vibration signature of a known successful operational event for a type of circuit breaker similar to that to be analyzed; and

    a processor cooperating with the accelerometer, first memory, storage, second memory and database, the processor configured to;

    determine the known mechanical vibration signature for the type of circuit breaker similar to that to be analyzed using the accelerometer to measure forces of mechanical vibrations along at least two axes that are generated adjacent a surface of the circuit breaker during the known successful operational event for the type of circuit breaker similar to that to be analyzed, wherein the type of circuit breaker similar to that to be analyzed has one or more known properties, wherein the one or more known properties include one or more of a new circuit breaker, a used circuit breaker, a circuit breaker operated in a test position, a circuit breaker operated in a location separate from a switchgear, a circuit breaker having sufficient vacuum seal, and a circuit breaker with a known defect;

    store the known mechanical vibration signature in the database;

    determine the measured mechanical vibration signature of the operational event for the circuit breaker to be analyzed using the accelerometer to measure forces of mechanical vibrations along at least two axes that are generated adjacent a surface of the circuit breaker to be analyzed during the operational event of the circuit breaker to be analyzed;

    store the measured mechanical vibrations in the storage; and

    compare the measurements of the forces of the mechanical vibrations generated at the surface of the circuit breaker during the operational event with the known mechanical vibration signature of the operational event to determine a mechanical status and/or a mechanical specific status of the circuit breaker based at least in part on the comparison.
