Latest Patents

Hoeweler's latest patents include a method and apparatus for compensation of phasor estimations. This method involves sampling a power system signal at specific intervals determined by the nominal power system frequency. The process generates a series of data samples that are used to estimate a phasor with an elliptical trajectory. A deviation formula is created to represent the frequency deviation between actual and nominal frequencies, allowing for a coordinate transformation of the estimated phasor into a scaled phasor with a circular trajectory. Additionally, if the data samples are unevenly spaced, an alternative method minimizes the squares of errors between the samples and an approximating sinusoidal function. This innovation is crucial for detecting turn faults by providing scaled current and voltage phasors, extracting fundamental phasors, and applying a symmetrical component transform.

Another significant patent is the self-tuning and compensating turn fault detector. This method detects turn faults in induction motors by obtaining and digitizing motor current and voltage waveforms. The fundamental phasors of these waveforms are extracted, and a symmetrical component transform is applied to obtain symmetrical component phasors, including negative sequence voltage and current phasors. This innovative approach enhances the sensitivity of fault detection, ensuring greater reliability in power systems.
