Jcalc arc flash
WebNov 14, 2024 · Arc flash occurs when electrical current becomes uncontrolled, and passes through an air gap between conductors in an attempt to “jump” from one conductor to another. This results in a release of electrical energy that ionizes the surrounding air, generating an enormous amount of light, heat, and sound. Okay, but what causes the … WebCalculating the incident energy for a DC arc flash begins with a simple application of Ohm’s Law: I = V ÷ R Where: I = Current in amperes (A) V = Voltage in volts (V) R = Resistance in ohms By including the DC arc resistance as part of the DC circuit model illustrated in Figure 1, you can easily determine the arcing current.
