Non-contact sensing and modelling on the voltage and electric field for powered transmission line

Abstract

From environmental, ecological or technical perspectives, the measurement of the potential voltage, electric field near the power transmission line is essential to ensure the exposure level does not exceed the limits of the government specified. This paper develops a potential voltage model, designs experiments to verify the developed model and to evaluate the parameters in the model. An electric field model is derived from the voltage model further, which can be used to estimate the electric field strength numerically. The models are found consistent with the observed data in the experiment.
