Materials for electrodes based on rare earth manganites

Solid State Ionics, 1994
Abstract For application in high temperature fuel cells and oxygen sensors, alkaline earth doped lanthanoide manganites have been studied systematically with regard to preparation conditions, structures, electrical conductivities and thermal expansion coefficients, respectively.

Lightning current distributions in a vertical earthing electrode

Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion (MedPower 2016), 2016
This paper presents a model for calculating current distribution in a vertical electrode and to the surrounding ground resulted by lightning. The model is based on electromagnetic field theory for calculating the response of the step wave-pair model. The physical parameters of the electrode such as the radius and length of the electrode is considered ...

Earth-electrode systems for large electric stations

Proceedings of the IEE Part A: Power Engineering, 1957
Interconnected systems have increased considerably in recent years, and the large possible earth-fault currents resulting require further thought being given to earth system design, especially in areas of high soil resistivity. The paper discusses the special practical problems of the design, construction and testing of earth electrode systems for ...

Grounding resistance of a single earthing electrode

Modern Problems of Telecommunications - 2024. Proceedings of Russian Scientific and Technical Conference
On traditional (copper) and fiber-optic communication lines, grounding is installed to protect the lives of workers and subscribers, as well as equipment and communication cables. For better protection, the grounding resistance should be low. Therefore, grounding is performed by a multi-electrode circuit of parallel connected single earth electrodes ...

Optimal Safety Earthing – Earth Electrode Sizing Using A Deterministic Approach

Journal of the Nigerian Association of Mathematical Physics, 2013
In this paper a deterministic approach in the sizing of earth electrode using the permissible touch voltage criteria is presented. The deterministic approach is effectively applied in the sizing of the length of earth rod required for the safe earthing of residential and facility buildings.
