MCSA (Motor Current Signature Analysis) is a well-established technique that relies on the same fundamental principle as MBVI systems, that the current drawn by a motor is affected by a number of factors, that each occur at specific, identifiable frequencies. MCSA is classically used for identifying rotor-bar problems in induction motors – a phenomenon that MBVI systems can also identify, with generally better resolution than MCSA.
However, MBVI systems are much more powerful than MCSA at identifying and diagnosing a wide range of phenomena. The key differences between MBVI systems and MCSA systems are:
