IEEJ Transactions on Electrical and Electronic Engineering, 2018
In this letter, we present a new single phase‐to‐ground fault feeder selector for a resonant grounded distribution system based on mathematical morphology. A combined morphological filter, which is the average of open–closing and close–opening, is employed to extract the transient component and decaying DC component from the zero‐sequence current ...

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 ...

Practical Experiences with Resonant Grounding in a Large 34.5-Ky System
Transactions of the American Institute of Electrical Engineers, 1950A large 34.5-kv system was operated ungrounded until early in 1946, at which time resonant grounding was installed, since it promised to be the most effective and most economical method of improving reliability of service. The layout of the system and a description of tests with the groundfault neutralizer installed are given. Records ords of operation

Ground and air resonance characteristics of a soft in-plane rigid-rotor system
VTOL Research, Design, and Operations Meeting, 1969A flight research program was conducted on a soft in‐plane matched‐stiffness rotor in which it was demonstrated that a soft in‐plane rigid rotor is subject to mechanical instability in flight as well as on the ground. The research included extending existing analysis techniques to include aerodynamic forces.
