First Claim
Patent Images
1. A control circuit for a power system comprising:
- a detection circuit that is coupled to an antenna and a filter circuit including a capacitor,wherein the antenna is configured to;
receive an electromagnetic wave generated by a brushfire in the power system;
convert the electromagnetic wave to an electrical signal; and
deliver the electrical signal to the detection circuit,wherein the detection circuit is configured to detect the brushfire based on the electrical signal, andwherein the filter circuit is configured to;
receive the electrical signal indicating the brushfire;
filter the electrical signal; and
deliver the electrical signal to the detection circuit.
