Harmonic voltage measurements using CVTs

IEEE Power Engineering Society General Meeting, 2004., 2005
A method for harmonic measurements in EHV systems is proposed that is based on the measurement of currents in capacitor voltage transformers (CVT) and values of capacitor elements of CVTs. This is the basis of a new technique, which uses current sensors installed within CVTs.

Considerations on probabilistic harmonic voltages

2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004
Some considerations on probabilistic harmonic voltages are given. Reference is made to modeling both for provisional analyses and to measurements for compliance with limits fixed by standards. Numerical and experimental case-studies are developed and analyzed.

Voltage harmonic distortion measurements using capacitive voltage transformers

Proceedings of IEEE. AFRICON '96, 2002
This paper investigates the application of capacitive voltage transformers (CVTs) for harmonic distortion measurements. Measured and simulated frequency responses are given for the voltage transformation ratio and the transconductance ratio of the capacitive divider ground return current and the high voltage input signal of a 400 kV CVT.

Harmonic Voltage Measurement based on Program Josephson Voltage Standard

2020 Conference on Precision Electromagnetic Measurements (CPEM), 2020
This paper investigates the feasibility of applying the program Josephson voltage standard to harmonic measurements. When using AC quantum voltage for harmonic voltage measurement, some data will fluctuate greatly due to the transition and Gibbs phenomenon.

Voltage harmonics compensator for high-voltage power supplies

2013 International Conference-Workshop Compatibility And Power Electronics, 2013
In this paper, a practical solution for suppression of voltage harmonics in high-voltage power supplies is proposed. The solution is based on three single-phase series active-power filters (SAPF) inserted in a common point of a synchronous generator (SG) through an injection transformer.
