For break arcs occurring between Ag contacts in nitrogen atmosphere, calculations of the thermodynamic and transport properties (electrical conductivity, viscosity, and specific heat at constant press
For the direct measurement of very fast transient current (VFTC) due to switch operation in gas insulated switchgear (GIS), usually it will interfere the original operation or change the structure of
In communication systems, electrical connectors could easily be subjected to contaminants in the atmospheric environments.The presence of the contaminants could lead to connector failure which is one
A sliding contact is the process of transferring the electrical current between a stationary and moving object, which for DC motors involves a brush (stationary) and a commutator slip ring (moving).Th
The thermal phenomena of the spring contacts in high-voltage apparatus is studied.An experimental circuit is built to conduct AC and DC steady-state temperature rise test with the spring contacts as t
A study has been undertaken of the temperature rise prediction for a medium voltage (MV) switching cabinet using a three dimensional finite element model.The features of key hardware components and fa
To develop the utilization of the ultra-high-frequency (UHF) method in partial discharge (PD) detection in gas insulated switchgear (GIS), it is necessary to study the propagation characteristics of E
