SUMMARY
This discussion focuses on measuring the power associated with a vertical rotating shaft, particularly in the context of vertical axis wind turbines. The formula for power is established as power = Torque * angular velocity. Angular velocity can be measured using a tachometer or spectroscope, while torque measurement can be achieved through two primary methods: using toothed wheels with magnetic pickups to analyze phase changes, or employing a scribed line on a torque tube observed under a strobe light and microscope. Both methods require a calibrated torque tube for accurate results.
