Abstract
A sensor for a separable connector comprises a plug body comprising an insulating resin, the plug body configured to be inserted into the separable connector to encase a high voltage conductor disposed in the separable connector. The sensor also includes one or more high voltage capacitors encased by the insulating resin and configured to be electrically coupled to the separable connector at a first end portion when the plug body is inserted and one or more low voltage capacitors electrically coupled in series to the one or more high voltage capacitors to form a capacitive voltage divider. The sensor also includes a low voltage connection configured to provide a low voltage signal corresponding to a high voltage signal present in the separable connector, the low voltage connection comprising a coaxial contact having a first metal contact and a second metal contact.
