Abstract
Methods and systems for a ground wire tone monitor, a multi-channel open loop ground wire tone monitoring system, and method for monitoring two or more ground wires in a power distribution system. A tone monitor includes a transmitter assembly and a receiver assembly. The receiver assembly on the power center communicates with the transmitter assembly on the machine side through a ground wire, so that this ground wire can be directly monitored, the location of the receiver and transmitter interchangeable. The multi-channel system includes up to 16-standalone tone monitor pairs used together to form a multi-channel system. Each tone monitor pair forms one channel in the multi-channel system and each channel operates on a unique preselected frequency. Filters are used to pass signals through to the receivers; the Amplitude of the signal is used to calculate the resistance of the ground wire.
