A novel full compensation method for the ground fault current of resonant grounded systems
Electrical Engineering, 2021The traditional arc suppression coil cannot compensate for the active and harmonic component of the ground fault current nor fully suppress the intermittent arc. For improvement, a novel full compensation method for the ground fault current of resonant grounded systems is proposed.

A Novel Measuring Method of Capacitance to Ground in Resonant Grounding System
2018 China International Conference on Electricity Distribution (CICED), 2018In order to accurately and effectively realize the arc-suppression coil tuning, it is urgent to improve the measuring accuracy of the capacitance to ground in resonant grounding system. Because the existing measuring method does not consider the damping resistance which is connected in the grounding loop of arc-suppression coil, a novel measuring ...

Systematic analysis of the harmonics in resonant grounding systems
2005 IEEE Russia Power Tech, 2005This paper deals with the causes, propagation and resonance phenomena of harmonics in the zero sequence currents and line-to-earth voltages of medium voltage (MV) networks with grounding via Peterson coils. Of special interest is the relation of these harmonics between normal and earth fault operation of the network.

2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018
The paper puts forward a recent practical issue which has never been addressed before that is associated with resonant grounded networks fed from multiple independent transformers and located in the same substation. This situation is common when the network is not initially designed as a resonant grounding network and the intention of using resonant ...

Application of Resonant Grounding in Power Systems in the United States
Transactions of the American Institute of Electrical Engineers, 1951Previous investigations indicated a trend toward increased application of resonant grounding in the United States. The application of resonant grounding in power systems operating at voltages from 2.4 kv to 230 kv has been analyzed on the basis of answers to a questionnaire received from all organizations using such grounding.

Effects of grounding on distribution system harmonic resonance conditions
IEEE Transactions on Power Delivery, 1989An analytic model is presented which predicts the impact of soil resistivity, grounding, and electric load on power system resonance characteristics. A parametric study is reported which illustrates the significance of these parameters and provides a quantitative evaluation of their effects.

A Ring Resonator System for Ground Subsurface Sensing
Subsurface Sensing Technologies and Applications, 2000A circular ring placed parallel above the ground surface is analyzed. The analysis, based on transmission-line modeling, shows how the structure can be utilized for ground conductivity sensing purposes. It is shown that, once the operating frequency is tuned to a half wavelength resonance, the information on the amplitude ratio of two voltages (or two ...
