Apparatus and method for monitoring power and current flow
First Claim
1. A method for monitoring and estimating power output of a power generation facility with multiple transmission lines operably connected thereto, comprising the steps of:
- placing at least one apparatus comprising a magnetic transducer and an electric transducer at a predetermined distance from each of the transmission lines in order to monitor each transmission line;
receiving electric and magnetic fields of each monitored transmission line with the apparatus associated with that transmission line;
processing said electric and magnetic fields to obtain information representative of magnitude and relative phase of said electric and magnetic fields;
determining power flow through each transmission line based on said information; and
estimating power output of the power generation facility based on the power flow through each transmission line.

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.
