Apparatus and method for monitoring power and current flow
DCFirst Claim
1. A system for monitoring information relating to a transmission line of a power generation facility, comprising:
- a central computing site; and
a monitor positioned at a location substantially remote to and at a predetermined distance from said transmission line, and without proximate access to said transmission line, said monitor includinga magnetic transducer for sensing a magnetic field associated with said transmission line,an electric transducer for sensing an electric field associated with said transmission line,a processor for receiving signals from the magnetic and electric transducers and generating data representative of the magnitude and relative phase of the respective magnetic and electric fields, anda means for transmitting said data to the central computing site.

Abstract
A method and system for remotely monitoring the magnitude and direction of net electrical power and current flow to or from a power generation facility over the transmission lines operably connected thereto allows for the estimation of the power output of that facility. The method includes detecting and measuring the magnetic field emanating from the monitored transmission line(s), and detecting a signal synchronized to the power system frequency, typically the electric field, emanating from the transmission lines. The method further includes evaluating, storing, and transmitting the data on the electromagnetic (EM) fields that are recorded.
