Abstract
A method of correcting the non-linearity of a sensor on a linear, high voltage power line comprises removably fixing a sensor on a conductor carrying an AC signal amplifying the current signal and calculating and calibrating a desired gain such that a non-linear signal from the sensor is converted to a linear signal.
