Measuring Electric Power with Digital Cycle Detection – Expert Talk at HBK

Cycle detection is one of the central elements in HBK Power Analyzers. This expert talk explains what cycle detection is all about and how it is used.

Cycle detection identifies the period that signals like torque, current, voltage, and others need to be averaged on to determine values of power, RMS and efficiency. This means that every point within that period will be accounted for during a calculation. If a signal, such as current or torque has harmonic content, that will also be included in the calculation. The exciting part about cycle detect is that you can get those values during transients. Every half cycle of the fundamental you view a high accuracy calculation which will enable a calibrator to account for harmonic content during changes in torque or speed. This can accelerate the job of the calibrator and give the calibration a higher quality. Cycle detect can be used to track individual harmonics to find trouble areas in a control.

What is cycle detection all about? How is it used? And in what way is it one of the central elements in HBK Power Analyzers?
