Abstract
Cavitation detection systems and methods include generating a signal representing the power factor of a motor driving a pump, analyzing the power factor signal and determining the presence of cavitation based on the analysis of the power factor signal. The power factor may be estimated using various estimation schemes. Analyzing the signal includes filtering the power factor signal.
