Non-contact bias voltage measurement using the electro-optic probing technique
Measurement Science and Technology, 2008The traditional non-contact electro-optic (EO) probing technique is further extended to measure quasi-dc bias voltages. We propose a special external LiTaO3 probe equipped with a grounded side-electrode (GSE) and a power supply modulation (PSM) method.

A Novel Non-contact Capacitive Probe for Common-Mode Voltage Measurement
IEICE Transactions on Communications, 2007This paper describes a capacitive voltage probe (CVP) that can measure a common-mode voltage on a cable without touching its conductor. This CVP has two coaxial electrodes: the inner electrode works as a voltage pickup and the outer one shields the inner electrode. These electrodes separate into two parts for clamping to the cable.

Study of Non-Contact and Non-Ground Voltage Signal Measurement System in Medium Voltage
IEEE Latin America Transactions, 2018The measurement of current and voltage (as well as the indexes derived from them) in the electricity distribution network becomes more and more necessary in the present day. The power concessionaires seek to distribute to their customers, reliability and stability in the supply of this energy with admissible levels of quality established by the ...

Non-contact transient high-voltage measurement with self-integrating D-dot probe
International Journal of Applied Electromagnetics and Mechanics, 2015Online transformer monitoring and protective relaying require voltage sensors with fast response and high precision. Traditional devices, such as resistive and capacitive dividers, have disadvantages in measuring transient voltage, e.g., oscillation, narrow bandwidth, and large size.
