ABSTRACT
Wind turbine maintenance operators and technicians generally have little difficulty in recognizing electrical equipment. Electrical equipment is everywhere within and is integral to wind turbines and electricity output. A question that does not always result in a resounding note of assurance, for the untrained wind turbine operator/maintenance technician, is for him or her to explain to people in very basic terms how electricity works to make their turbine equipment operate and generate; the answers people would receive would be varied, jumbled, disjointed—and probably not all that accurate. The word electricity is derived from the Greek word “electron”. Scientists have determined that electricity seems to behave in a constant and predictable manner in given situations or when subjected to given conditions. Scientists, like Faraday, Ohm, Lenz, and Kirchhoff, have described the predictable characteristics of electricity and electric current in the form of certain rules.
