The Scope and Application of Electrical Signature Analysis in Windpower
Electrical Signature Analysis (ESA) was initially developed at Oak Ridge National Labs (ORNL) in the 1980s as a method for evaluating bearings and gears in motor operated valves in the nuclear power industry. In 1992, the technology was licensed into general industry for applications in utilities and commercial applications...
