US Patent:

20120046799, Feb 23, 2012

Filed:

Apr 29, 2010

Appl. No.:

13/266618

Inventors:

Paul Alan Alex - Fairfield CT, US
Duncan Breese - New Milford CT, US
Larry Fish - White Plains NY, US
Charles Lipsky - Cortlandt Manor NY, US
Chunchuan Xu - Hartsdale NY, US

International Classification:

G05B 15/02

US Classification:

700298

Abstract:

A device for monitoring and measuring the electrical and mechanical parameters of a power line conductor. Sensors of the device measure conductor temperature, the angle of inclination of the overhead conductor, current flowing in the conductor, and voltage to ground. The device has a low-power mode in which parameters of the power line conductor are not measured. Upon detecting a change in an electrical or mechanical value of the power line conductor, the device measures parameters of the power line conductor for a predetermined length of time before returning to the low power mode.

International Classification:

G01V 9/00

Abstract:

Techniques are described for generating earth sub-surface thermal characteristics over an area include collecting real-time weather data and earth data for a plurality of locations associated with an underground electrical cable and calculating earth thermal properties at the plurality of locations based on the real-time weather data and the measured earth data by an iterative process. The calculated earth thermal properties at two or more of the plurality of locations are interpolated to determine interpolated earth thermal properties at another location associated with the underground electrical cable and a wide-area thermal property map created from at least some of the calculated earth thermal properties and the interpolated earth thermal properties.
