Evaluating wind-turbine generators through electrical signature analysis
By Howard W Penrose, Ph.D., CMRP President | MotorDoc LLC Properly assessing an operating turbine’s electrical and mechanical systems is no easy task. An electrical signature analysis or ESA is independent of load or speed, so the test is often applied to analyze generators and electric equipment. Still, a challenge is to ensure loading stays constant…
