Abstract

A power supply extracts electrical power from the electro-magnetic field surrounding a high voltage power conductor and conditions the derived input power to provide a stable power source for instrumentation and communications equipment. The communications controller is a local network router that routes serial data traffic to selected communication devices such as an instrumentation processor, a power supply processor, or a maintenance port controller. The router forwards the data to other communications equipment and forwards data from the communicating equipment to an external network providing substantially simultaneous communications between the external network and the instrumentation processor, power supply processor and maintenance port controller.

Claims

1. A method for monitoring a power line conductor comprising:

storing in an energy storage device a portion of power induced from an electric field of the power line conductor resulting from current flowing in the power line conductor;

using a first instrument platform to sense at least one data parameter associated with the power line conductor; and

communicating the at least one data parameter to a second instrument platform,

using the second instrument platform to sense a data parameter associated with the power line conductor;

analyzing, at the second instrument platform, the at least one data parameter of the first instrument platform and the data parameter of the second instrument platform,

communicating, from the second instrument platform, the analyzed at least one data parameter of the first instrument platform and the data parameter analyzed at the second instrument platform to a third instrument platform,

wherein the third instrument platform communicates the analyzed at least one data parameter of the first instrument platform and the data parameter analyzed at the second instrument platform with a ground-based processor;

wherein when current flowing through the power line conductor is below a first predetermined threshold value, the energy storage device provides power for the instrument platform,

wherein when current flowing through the power line conductor is above the first threshold value and below a second threshold value, the electric field of the power line conductor provides power for the instrument platform and does not provide power to charge the energy storage device, and

wherein when current flowing through the power line conductor is above a second predetermined threshold value greater than the first predetermined threshold value, the electric field of the power line conductor provides charging current to the energy storage device.

2. The method of claim 1, wherein the instrument platform senses a plurality of data parameters.

3. An system for monitoring a power line conductor comprising:

an energy storage device to store a portion of power induced from an electric field of the power line conductor resulting from current flowing in the power line conductor;

a first instrument platform to a sense at least one data parameter associated with the power line conductor; and

a first communication device disposed in the first instrument platform to communicate the at least one data parameter to a second instrument platform,

wherein the second instrument platform is enabled to sense a data parameter associated with the power line conductor,

an analyzing device disposed in the second instrument platform to analyze, at the second instrument platform, the at least one data parameter of the first instrument platform and the data parameter of the second instrument platform,

a second communication device disposed in the second instrument platform to communicate, from the second instrument platform, the analyzed at least one data parameter of the first instrument platform and the data parameter analyzed at the second instrument platform to a third instrument platform,

wherein the third instrument platform is enabled to communicate the analyzed at least one data parameter of the first instrument platform and the data parameter analyzed at the second instrument platform with a ground-based processor

wherein when current flowing through the power line conductor is below a first predetermined threshold value, the energy storage device provides power for the instrument platform,

wherein when current flowing through the power line conductor is above the first threshold value and below a second threshold value, the electric field of the power line conductor provides power for the instrument platform and does not provide power to charge the energy storage device, and

wherein when current flowing through the power line conductor is above a second predetermined threshold value greater than the first predetermined threshold value, the electric field of the power line conductor provides charging current to the energy storage device.
