Patent ID: 7795877

Claim:
A power line communication device for providing information related to a un-insulated medium voltage power line carrying power with a voltage greater than one thousand volts, comprising: a first current sensor device configured to be physically attached to the un-insulated medium voltage power line and to measure the current of the un-insulated medium voltage power line; said first current sensor device including a data interface, an analog-to-digital converter (ADC), and a memory; said first current sensor device including a processor in communication with said memory, said ADC and said data interface; wherein said processor is programmed to receive data representing the measured current carried by the un-insulated medium voltage power line; wherein said processor is programmed to store data of a plurality of current measurements in said memory; wherein said processor is programmed to retrieve the plurality of measurements from memory and to cause said data interface to transmit the data representing the plurality of measurements in a single transmission; a second device configured to be mounted to a utility pole and comprising: a sensor interface configured to communicate with said data interface of said first current sensor device; a modem configured to transmit data related to the measured current; a controller communicatively coupled to said modem and said sensor interface and having a memory with executable program code stored in said memory; and wherein said first current sensor device is electrically isolated from said second device.
