Electrical Signature Testing and Analysis

Electric Signature Analysis (ESA) is a technique for analyzing motors, generators, alternators, transformers, and other electric equipment. The technology can test operating electrical equipment and identify several mechanical and electrical problems. ESA is remote, non-intrusive, and invisible to the monitored equipment. ESA traces can analyze the driven load, the power supply, and perform inrush testing. As a preventative-maintenance tool, you use ESA for either single or periodic testing to track equipment performance. Monitoring a parameter of conditionin order to identify a significant change which is indicative of a developing fault.It is a major component of predictive maintenance.The use allows maintenance to be scheduled, or other actions to be taken to prevent failure and avoid its consequences. Testing and analysis has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure.
