System and method for an arc fault detector
First Claim
1. A method of communicating over a power line, the method comprising:
- communicating a power line signal over the power line, wherein the power line signal comprises a communication signal modulated on an alternating current (AC) power signal; and
performing arc fault detection processing on the power line signal, wherein the arc fault detection processing is performed taking into account a characteristic of the power line signal.

Abstract
Embodiments of the present disclosure include a method of operating an arc fault detection system, an arc fault detection system, and a system. An embodiment is a method of operating an arc fault detection system coupled to a power line, the method including determining one or more arc fault detection windows in power line signals on the power line, the power line signals comprising a communication signal and an alternating current (AC) power signal. The method further includes receiving the power line signals from the power line during the one or more arc fault detection windows, and performing arc fault detection processing on the received power line signals.
