Abstract
A power distribution monitoring system is provided that can include a number of features. The system can include a plurality of monitoring devices configured to attach to individual conductors on a power grid distribution network. In some embodiments, a monitoring device is disposed on each conductor of a three-phase network. The monitoring devices can be configured to measure and monitor, among other things, current and electric-field on the conductors. Methods of calibrating the monitoring devices to accurately measure electric-field are also provided. In one embodiment, a first monitoring device on a first conductor can transmit a calibration pulse to a second monitoring device on a second conductor. The second monitoring device can determine a degradation of the calibration pulse, and use that degradation to calibrate electric-field measurements around the conductor.
