Latest Patents

One of Ashby's latest patents is a "System and method to measure neutral-to-ground voltage." This invention provides a method and program for minimizing objectionable currents while still allowing for accurate neutral-to-ground voltage measurements. It achieves this by controlling a switch to determine when the neutral-to-ground impedance is placed in an electrical circuit.

Another significant patent is the "Method and apparatus for synchronizing data in utility systems." This invention features a time synchronization device (TSD) that produces a synchronization signal and couples it onto energized power conductors within a power monitoring system. The TSD is equipped with frequency detection algorithms, such as a Goertzel filter, to detect the synchronization signal and interpret the information encoded within it. The synchronization signal's frequency may correspond to the fourth or tenth harmonic component of the fundamental frequency of the voltage on the power conductors. The signal's magnitude is designed to exceed the expected noise floor of the power monitoring system, plus a predetermined threshold. The duration of the signal can be varied, potentially lasting a full cycle of the fundamental frequency. Multiple TSD signals received in a predetermined sequence can be converted into digital words that convey time, configuration, reset, control, or other information to the monitoring device.
