Abstract: A method is for analyzing the correlation between different line loss actions, which records, for each individual to which line loss actions occur, all the line loss actions that occur to the individual; and counts, based on two categorization manners: by individual and by line loss action, line loss actions recorded in the database, to obtain line loss action counting results corresponding to respective categorization manners; then, based on the two counting results, collects respective multi-line loss action sequences; and acquires probability data as a data source for probability calculation, to obtain line loss action occurrence conditional probabilities for different line loss actions, so that a targeted a targeted loss reduction plan can be formulated.

Abstract: An electronic current transformer for measuring currents includes a shielding structure, TMR sensor, conductor, amplification circuit, and circuit board. The shielding structure comprises a material that protects the sensor from external disturbance and damps the magnetic field from the internal conductor. The TMR sensor is connected to the amplification circuit for electric current measurement by means of reconstruction of magnetic field measurement. The TMR sensor is configured to receive data from the conductor and to transmit the data to the amplification circuit, which is configured to amplify the data and release the data as an output of the transformer.

Abstract: The invention discloses a monitoring system for estimation of phase conductor parameters of overhead high voltage transmission lines. Particularly, these parameters include electric current, conductor clearance from ground and wind induced conductor motion. This is realized by utilizing magnetic field sensing at various points or of various components with state of art Tunnel Magneto resistive sensors. The measured data is then divided into two groups, where one group performs the reconstruction using magnetic field and the other group validates the reconstructed results. For each group, initial conductor to sensor position coefficients are stored in two different sensitivity matrices in memory. For a change in conductor spatial position, the sensitivity matrices are altered which is estimated for each group and then validated by comparison. Errors in the reconstruction process are minimized by sensor placement at optimal points which ensures the condition number remains close to unity.
