“…When a series-arc fault occurs, radio frequency emission, infrared radiation, acoustic signals (audible sound) and deformation of current and voltage signals can be seen as the main physical features [2,10]. Out of the above parameters, the deformation of current and voltage signals produces significant results.…”

The main cause of electrical fires, which is more severe in nature than non-electrical fires, is the series-arc fault. In this paper, the properties of series-arc faults are studied and the parameters affecting the risk of domestic electrical fires are analysed. In particular, a series-arc fault generator, made to align with the international standards, is used to study the characteristics of seriesarc faults in a domestic electrical installation. The waveforms of common domestic equipment, in the absence of a fault and in the presence of a fault, are examined in detail. It is seen that arc current waveform can be identified as having a vertical edge appearing after the zero-crossing point. Further, the impact of series-arc faults on igniting a fire in domestic electrical installations are analysed using thermal imaging. Finally, ability of the most commonly used insulation materials which may aid the initiation of electrical fires due to the series-arc faults has thermally categorized. The study has shown that even a 2A arc current that is sustained for 2s can auto-ignite PVC, the most common insulation material in domestic installations.

“…Such an arrangement without the metallic flux concentrator has been demonstrated for interrupting a quasi D.C. current [9]. The B-field producing coil in such a concentric cylinders arrangement (without a flux concentrator) has been independently activated from the quasi-direct arc current between the anode and cathode using a resistor-inductorcapacitor (RLC) circuit connected across the arc gap.…”

“…Interruption of a quasi-direct current (600A initial value) with a convoluted arc device, without a flux concentrator(Fig. 1); Operational conditions: Interrupter gas -atmospheric pressure air, B-field coil (150mT) energized separately with a current of 5.8kA, Outer PTFE cylinder -inserted around the device; R, L, C circuit connected across the arc gap to produce arc current and voltage frequency oscillations of 2kHz[9]). Variations produced by a separately activated B-field coil, (a) Lorentz Force vs coil current, (b) Time of current interruption vs coil current.…”

Further considerations are given to the use of an electromagnetic flux concentrator for arc plasma control in a rotary arc current interrupter. Such flux concentrators have been previously proposed for plasma fusion and other plasma applications. The possible extension of the proposed method for enhancing the interruption of direct currents with a rotary arc interrupter is discussed with the aid of theoretical modelling of the concentrator geometry and with its possible enhancement of ablation from the arc containing cylinders.
