  • WEATHER RESISTANT UNGROUNDED POWER LINE SENSOR
    Publication number: 20160370408
    Abstract: An ungrounded power line sensor system includes a housing configured for coupling about a power line, at least a first voltage sensing plate supported by the housing and exposed to rain and snow, and at least a second voltage sensing plate supported by the housing and shielded from rain and snow. Voltages sensed by the first and second voltage sensing plate are separately measured in order to mitigate variations in the two measurements due to a weather event, for example by applying a weighted average calculation to the measurements to cancel out the effects of rain on the first voltage sensing plate.
