SENSOR, METHOD AND SYSTEM FOR MONITORING POWER LINES Russian patent published in 2011 - IPC G01R15/14

Abstract RU 2437105 C2

FIELD: physics.

SUBSTANCE: magnetic fields are picked up with coils lying sufficiently close to the lines for measuring voltage induced by into the coils without contact with the lines. Components x and y of magnetic fields are used to calculate wire sag, and data on sag together with data on field intensity can be used to calculate the current load on the line and the current phase. Calculation of sag using this invention is independent of the measured voltage across the line and current in the line.

EFFECT: high accuracy.
