Abstract

The modified Mayr arc model, in which the arc time constant and arc power loss are dependent on the arc conductance transition near current zero, were investigated. The interrupting capability and phenomena are much affected by the index parameters of the equation between the arc time constant and the arc conductance. The simulation results of the loop current interruption by the interrupters with low parallel resistance using the modified Mayr model showed good coincidence with experimental data.
