Numerical modelling is widely used in the study of energy exchange between the arc and gas flow in arc-quenching devices of gas-operated high-voltage circuit breakers. In the high-current phase, the main factor influencing the energy exchange is radiation. In this paper a study of different radiation models and their analysis is carried out. The description of the considered radiation models and their implementation in COMSOL Multiphysics are given. The comparison of calculated results obtained using different models with experimental data is carried out. Recommendations on the use of the models are formulated. Keywords: switching arc, high-current phase, numerical modeling, radiation.
