Embodiment Construction

[0027] Example embodiments are described in detail below with reference to the accompanying drawings, wherein like reference numerals refer to like parts throughout. Some of these embodiments can address the above and other needs.

[0028] refer to figure 1 , shows the power system and is generally indicated by reference numeral 100 . Power system 100 includes a power source 102 configured to deliver power to a load 104 via a circuit breaker 106 . For example, power source 102 can deliver alternating current (AC) power to common bus 108 using a three-phase configuration as shown or, for example, via a single-phase configuration. The power source 102 and the load 104 can also be coupled to an arc mitigation device 110 via a common bus 108 . The arc mitigation device 110 can be enclosed within an arc containment device 112 .

[0029] Electrical signal monitoring system 114 can be configured to monitor electrical current changes in power system 100 that may occur due to arc f...

Abstract

Provided is an apparatus, such as an arc mitigating device, that includes an annular body that defines a lumen and a longitudinal axis, the annular body having a body length along the longitudinal axis. An electrode can be disposed coaxially within the lumen. The electrode may extend into the body by an electrode length that is at least about 50% of the body length, and may have diameter less than or equal to about 50% of an inner diameter of the annular body. An ablative material portion can be disposed between the annular body and the electrode. The annular body and the electrode may be configured such that when an arc exists between the annular body and the electrode, the ablative material portion undergoes ablation and thereby generates a plasma.

Description

technical field [0001] Embodiments presented herein relate generally to plasma guns and, more specifically, to ablative plasma guns. Background technique [0002] Power circuits and switchgear typically involve conductors separated by insulation. In some areas, air gaps often act as part or all of this insulation. Arcing can occur between conductors if the conductors are too close to each other or if the voltage difference exceeds the insulation performance. The air or any insulation (gas or solid dielectric) between the conductors may become ionized, making the insulation conductive and thereby enabling arcing. Arc temperatures can reach as high as 20,000°C, vaporizing conductors and adjacent materials, and releasing explosive energy that can destroy circuits. [0003] Arc flash is the result of a rapid release of energy caused by an arcing fault between phase-to-phase, phase-to-neutral, or phase-to-earth. An arc flash can produce high heat, intense light, pressure wave...
