Abstract
A voltage sensor for measuring the voltage on high voltage lines is formed by an electrically isolating-section of material with resistive shielding (RS) that structures the electric field generated by a voltage difference between the two ends of the isolating-section and provides shielding of the internal electric field from sources of electric field interference external to the voltage sensor. At least one electric field sensor is provided to sense the electric field in the isolating-section the output(s) of which is(are) used to infer the voltage difference.
