• This paper proposes the P-1 radiation model for the calculation of low voltage arc plasma. The influence of both emission and self-absorption are taken into account in this model. Based on the couple of electric field, magnetic field, flow field and thermal field, a three-dimensional arc chamber model is constructed and its radiation energy is calculated by the P-1 model with the spectrum divided into six bands. From the obtained distributions of temperature, incident radiation intensity, plasma velocity and current density by P-1 model, it is observed that temperature is obviously different from the result by net emission coefficient (NEC) method in the low temperature region. Arc column edges near the arc root also absorb radiation energy. Furthermore, compared with the result by NEC method, the arc column voltage calculated by P-1 model is lower and more close to the experimental result.
