Development of electrodes based on yttrium chromites and rare earth doped hafnia for MHD generator applications

open access: yes, 1979
Yttrium chromites are being studied as potential high temperature electrodes for MHD. Like lanthanum chromites, the doped yttrium chromites have similar high electrical conductivity, predominantly electronic over a wide temperature range; however, they ...

A method to evaluate voltages to earth during an earth fault on a HV network in a system of interconnected earth electrodes of MV/LV substations

open access: yes, 2004
An easy and fast method to evaluate, in a system of interconnected earth electrodes, earth potentials on earthing systems of medium voltage/low voltage (MV/LV) substations, in event of single-line-to-earth fault on a high voltage/medium voltage (HV/MV ...

Soil ionization due to high pulse transient currents leaked by earth electrodes

open access: yes, 2009
This paper proposes a numerical model of the soil ionization phenomena that can occur when earth electrodes are injected by high pulse transient currents, as the one associated with a direct lightning stroke.

Performance of lightweight nickel electrodes

open access: yes, 1988
The NASA Lewis Research Center is currently developing nickel electrodes for nickel-hydrogen (Ni-H2) batteries. These electrodes are lighter in weight and have higher energy densities than the heavier state-of-the-art (SOA) sintered nickel electrodes. In

Designing an earth electrode for distribution substations

open access: yes, 2009
In electrical engineering, the term ground or earth has several meanings depending on the specific application areas. Ground is the reference point in an electrical circuit from which other voltages are measured, a common return path for electrical ...
