Non-Contact Measurement of Line Voltage
IEEE Sensors Journal, 2016This paper presents a capacitively coupled non-contact voltage sensor, which is specifically optimized for monitoring line voltages ranging from plug level to distribution levels at thousands of volts. The sensor uses a new arrangement of electrostatic pickups to measure the rate of change of an unknown potential, and digitally integrates that the rate

Current and Voltage Reconstruction From Non-Contact Field Measurements
IEEE Sensors Journal, 2016Non-contact electromagnetic field sensors can monitor voltage and current in multiple-conductor cables from a distance. Knowledge of the cable and sensor geometry is generally required to determine the transformation that recovers voltages and currents from the sensed electromagnetic fields.

Dual capacitive sensors for non-contact AC voltage measurement
Sensors and Actuators A: Physical, 2011Abstract Non-contact voltage sensors are designed to detect the voltage in a wire or piece of equipment without actually making direct contact with the conductor or energized part. Conventional single capacitive probe approach is not accurate and could easily be affected by environmental factors.

Non-contact measurement of dc voltages using nonlinear elements
Measurement Science and Technology, 2012In this work, it is shown that dc voltages may be measured via a capacitive interface, provided that the capacitance between the measurement system and the dc voltage source being measured is nonlinearized. This nonlinearization is achieved by the addition of a nonlinear capacitor in series with the coupling capacitance.
