A Novel Measuring Method of Capacitance to Ground in Resonant Grounding System

2018 China International Conference on Electricity Distribution (CICED), 2018
In 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 ...

Experience with Resonant Grounding in a Large 34.5-kY System

IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1966
Since early 1946, when grounding of the 34.5-kV system of the Wisconsin Michigan Power Company was established through installation of a Peterson coil, very complete records have been maintained with regard to all ground faults on the system. The results of an analysis of these records, covering 19 years of operation with resonant grounding, are ...

Resonance Analysis and Faulty Feeder Identification of High-Impedance Faults in a Resonant Grounding System

IEEE Transactions on Power Delivery, 2017
High-impedance faults (HIF) occur frequently in resonant grounding systems and are difficult to detect. Thus, an effective HIF feeder identification technology is urgently needed. This paper establishes an HIF equivalent circuit in a resonant grounding system.

A novel full compensation method for the ground fault current of resonant grounded systems

Electrical Engineering, 2021
The 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.

Resonant grounding of american power systems

Electrical Engineering, 1951
THE LATEST AIEE Committee Report on Grounding Practices1 indicated a trend toward increased use of Petersen coils in high-voltage power systems in this country. A study was undertaken to analyze the application of resonant grounding and questionnaires were sent to all operators using Petersen coils.
