“…It yields to 18 V for copper cables, and 19 V for aluminum cables in the case of DC current as shown in figure 3. The accuracy of these values is rather low but they correspond quite well to values found in literature [2,3]. Similar measurements were performed in AC for the three tested currents, but the method is less accurate due to the more unstable behavior of the arc, the orientation of the plasma plume changing every half period.…”

“…In particular, short circuits occurring between two adjacent cables may lead to a particular phenomenon called "arc tracking" [1,2] corresponding to the propagation of the arc along the cables due to the cable metallic core ablation and to the surrounding dielectric material degradation. In traditional aircrafts, one solution consists in using copper cables with appropriate insulating material mainly composed of polytetrafluoroethylene (PTFE), a fluorocarbon polymer.…”

Abstract. Arc tracking tests have been carried out between two voluntarily damaged aeronautic cables. Copper or aluminum conductors have been exposed to short circuits under alternating current. Various data have been recorded (arc voltage and current, radiated power and ablated mass), enabling to determine a power balance, in which every contribution is estimated. The total power is mainly transferred to the cables (between 50 and 65%, depending on the current and the cable type), and causes the melting and partial vaporization of the metallic core and insulating material, or is conducted or radiated. The other part is deposited into the arc column, being either radiated, convected or conducted.

“…Arc tracking is a phenomenon in which due to the degradation of insulation, a micro-arc may be initiated, sustain itself, and propagate along the electrical wires [35], thus generating more damage to the insulation. It appears as a short circuit between adjacent wires and is a critical issue for aeronautics safety [36] since it generates a risk of fire and explosion [37]. It is also known that the current pulses, due to the arc tracking effect, cover a wide band, so it can disturb communication or control systems due to the electromagnetic coupling with other wires [35].…”

Visual corona tests have been broadly applied for identifying the critical corona points of diverse high-voltage devices, although other approaches based on partial discharge or radio interference voltage measurements are also widely applied to detect corona activity. Nevertheless, these two techniques must be applied in screened laboratories, which are scarce and expensive, require sophisticated instrumentation, and typically do not allow location of the discharge points. This paper describes the detection of the visual corona and location of the critical corona points of a sphere-plane gap configurations under different pressure conditions ranging from 100 to 20 kPa, covering the pressures typically found in aeronautic environments. The corona detection is made with a low-cost CMOS imaging sensor from both the visible and ultraviolet (UV) spectrum, which allows detection of the discharge points and their locations, thus significantly reducing the complexity and costs of the instrumentation required while preserving the sensitivity and accuracy of the measurements. The approach proposed in this paper can be applied in aerospace applications to prevent the arc tracking phenomenon, which can lead to catastrophic consequences since there is not a clear protection solution, due to the low levels of leakage current involved in the pre-arc phenomenon.

In case of a short-circuit between two wires of a dc line, a sustained arc may occur and propagate along the wires through pyrolization of the insulation. This phenomenon, known as arc tracking, is quite critical from a safety point of view since it can cause fire or explosion, depending on its close environment. In addition, the arc generates conducted electromagnetic noise in a wide frequency range which can couple to other wires situated either in the same cable bundle or in its vicinity and disturb control/command devices. In this paper, only this last point is considered, the objective being to characterize the spectral density of the voltage and current generated by such an arc tracking in a high-frequency band extending from 300 kHz to 30 MHz. First, the measurement set up is described, emphasizing the key points to deduce the intrinsic characteristics of the arc from the measured values. A Thevenin generator equivalent to the arc is proposed in order to be able, in a further step, to predict disturbing noise at any point of the cable network.Index Terms-Aircraft electronics, arc discharges, electromagnetic conductive interference, high-voltage dc (HVdc) transmission lines, noise measurement.
