Latest Patents

One of Hinman's latest patents is titled "Method and apparatus for monitoring an AC transmission line." This invention focuses on an improved method for monitoring the status of an AC electrical transmission line connected between two locations. The method involves generating first signal parameter values at the first location by time integrating between zero-crossings of an AC signal parameter. Similarly, second signal parameter values are generated at the second location and transmitted back to the first location. This technique optimizes bandwidth usage without compromising the tripping response time.

Another significant patent is "Unsupervised trip keying for phase comparison relaying apparatus." This invention relates to phase comparison relaying apparatus at local and remote terminals of a protected line section. It employs unsupervised circuitry to generate an echo trip signal, which is crucial for effecting breaker tripping at the opposite terminal. The additional circuitry supervises the generation of a breaker trip signal, ensuring effective operation even during open breaker or zero-feed conditions.
