Analytical modelling of arc re-ignition conditions on polluted insulating surfaces

2018 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2018
The main propose of this paper is the elaboration of an analytical relationship of arc dry-band re-ignition condition of HVAC polluted insulators. The model is based on the equivalent electrical circuit of polluted insulator and the thermal proprieties of the dryband arc.

Experimental study of the decay and re-ignition of a recombining arc discharge

Journal of Physics D: Applied Physics, 1982
Better knowledge of arc decay and re-ignition is needed for the improvement of circuit breakers. A simple but high performance device is used to study the behaviour of a wall stabilised arc submitted to recurring decay and re-ignition. It is shown that for a definite short-circuit time the arc reveals a delay between voltage and current recovery.

Post-arc Current and Re-ignition after Many Interruptions by MCCB and the Endurance

IEEJ Transactions on Power and Energy, 2003
The purpose of this investigation is experimental research of many interruption performance for Molded Case Circuit Breaker (MCCB) currently used for the protection of a low voltage circuit. It is anticipated by interruption especially by high current many interruptions that the interruption performance will decrease.

An Active Limit Baffle for the Phenomenon of Arc Instability and Re-ignition

2019 IEEE Holm Conference on Electrical Contacts, 2019
The arc instability and re-ignition refers to the arc cannot maintain a stable state or the arc extinguished but re-burn quickly. When a normally open relay releases, its movable contact, static contact, as well as their reeds are free, especially the movable contact of which energy cannot be dissipated immediately.

Modelling of short arc re-ignition

Journal of Physics D: Applied Physics, 1993
A unified mathematical description of phenomena leading to short arc re-ignition is presented. Computational results for a 2 mm long post-arc channel appearing at current zero after the burning of a 900 A arc on silver electrodes are discussed. The analysis concerns both cathode and anode electrode layers, for which computations were run simultaneously.

Thermal re-ignition processes of switching arcs with various gas-blast using voltage application highly controlled by powersemiconductors

Journal of Physics D: Applied Physics, 2018
This paper focuses on a fundamental experimental approach to thermal arc re-ignition processes in a variety of gas flows in a nozzle. Using power semiconductor switches in the experimental system, the arc current and the voltage applied to the arc were controlled with precise timing.

Behaviour of short-circuit frequency and duration time and electrical conductivity during arc re-ignition in SMAW (AC) with E6013 electrodes

Welding International, 2010
The objective of this work is to evaluate the behaviour of short-circuit frequency and duration time and electrical conductivity during arc re-ignition in the shielded metal arc welding process with alternating current and E6013 electrodes. The non-parametric statistical analysis guarantees robust processing of the data, reducing the influence of ...
