Title: Innovations of Kung C Chow
Introduction
Kung C Chow is a notable inventor based in Coral Springs, Florida. He holds five patents that showcase his contributions to the field of electrical engineering and power systems. His work focuses on enhancing the reliability and efficiency of power transmission components.
Latest Patents
One of his latest patents is the "Sub-cycle digital distance relay." This invention utilizes only the first N/2 samples after a fault to calculate the distance to the fault using a Full Cycle Fourier Algorithm. The relay operates on N samples, where N represents the number of samples taken in a cycle of the power signal. The DC offset in the first N/2 samples is canceled using the N/2+1 sample taken after the fault detection. This method allows the digital distance relay to estimate the distance to the fault and provide a reliable trip signal in less than one cycle of the power signal. This technique significantly improves fault protection for power transmission components.
Another significant patent is the "Apparatus for detecting unsymmetrical bipolar waveforms." This apparatus detects a predetermined unsymmetry of a bipolar waveform through a circuit that generates a pulse for each zero crossing of the waveform. The design includes retriggerable one-shots that time out at specific intervals, indicating a predetermined unsymmetry based on the relative values of these intervals. This invention is particularly useful in blocking false trip signals from reverse current relays when transformers are energized with little or no load.
