A comparative study of modelling AC electric arc by one-dimensional interpolation for power system harmonics analysis

MATEC Web of Conferences, 2016
Electric arc is a discharge phenomenon caused by particular electrical events and arc produced facilities in power system, for example the occurrence of short-circuit fault in feeders and the use of electric arc furnace for steel-making.

Motion behavior of a high-current fault electric arc occurred in the dead zone of protection in a substation

Frontiers in Energy Research
Since the dead-zone fault in substations often has a relatively long removal time, it may damage the insulation of power equipment and even threaten the stability of the power system.

Electric Arc Surfacing of Defective Plots of Rails in the Area of Electrocontact Welded Joint [PDF]

MATEC Web of Conferences, 2019
One of the main causes for the failure of the rails of a continuous joint made by electric contact welding is defects in collapse and wear in the joint zone. We address the usage of electric arc surfacing to repair defective rails.
