Devices, systems, and methods for adaptive RF sensing in arc fault detection
View Patent ↗A method for arc fault detection, includes automatically generating an output signal responsive to an input signal. The input signal is indicative of an arc fault. The output signal is configured to cause an electrical circuit to open. The output signal is generated responsive to a derived signal based upon a first threshold having a first amplitude.
1. A machine-readable medium encoded with machine instructions, the machine-readable medium defining steps comprising:
automatically generating an output signal responsive to an input signal, said input signal indicative of an arc fault, said output signal configured to cause an electrical circuit to open, said output signal generated responsive to a derived signal based upon a first threshold having a first amplitude, said first threshold changed from said first amplitude to a second amplitude if a predetermined percentage of historical sampled values of a measured electrical parameter are within a predetermined range during a predetermined time period, said second amplitude for said first threshold based upon an average of a predetermined count of said historical sampled values of said measured electrical parameter.
2. A system comprising:
a processor configured to:
automatically generating an output signal responsive to an input signal, said input signal indicative of an arc fault, said output signal configured to cause an electrical circuit to open, said output signal generated responsive to a derived signal based upon a first threshold having a first amplitude, said first threshold changed from said first amplitude to a second amplitude if a predetermined percentage of historical sampled values of a measured electrical parameter are within a predetermined range during a predetermined time period, said second amplitude for said first threshold based upon an average of a predetermined count of said historical sampled values of said measured electrical parameter.
3. The system of claim 2 , further comprising:
a circuit breaker comprising said processor.
4. The system of claim 2 , further comprising:
a device configured to open said electrical circuit responsive to said output signal.
