Abstract
Methods and apparatus for measuring the voltage of at least one conductor () of an electrical power cable () comprise providing a container () made from a conductive material around a portion of the cable and at least one electric field sensor () between the container and the cable and bringing the container to a constant potential and measuring the electric field with a sensor. The voltage is determined by comparing the measured electric field with electric fields simulated for a plurality of configurations of punctual electric charges.
