1. A system, comprising:
a non-intrusive capacitive voltage sensor configured to couple to an insulator surrounding a metal conductor, wherein the non-intrusive capacitive voltage sensor is configured to produce a voltage signal indicative of a voltage in the metal conductor, the non-intrusive capacitive voltage sensor, comprising:
an arcuate body comprising separation between two peripheral end portions of the body, wherein the separation is configured to enable the body to couple to the insulator in a lateral direction relative to an axis of the metal conductor, wherein the body is configured to extend circumferentially along a surface of the insulator;a signal plate configured to create a capacitor with an outer surface of the metal conductor;a magnetic shield plate configured to block magnetic field interference with the signal plate;an electric shield plate configured to block electric field interference with the signal plate, wherein the electric shield plate is separate from the magnetic shield plate; andinsulating material disposed between the signal plate and the magnetic shield plate;wherein the arcuate body, the signal plate, the insulating material, the magnetic shield, and the electric shield are coupled together; and a monitor-controller system configured to receive the voltage signal from the non-intrusive capacitive voltage sensor, wherein the monitor-controller system is configured to use the voltage signal to monitor or control a machine. |
