Abstract :
Secondary arcs can be modeled in a numerical transients program like ATP-EMTP. The dynamic behavior of the arc is represented as a time-varying resistance by solving a differential equation of arc conductance based on the energy balance in the arc column. The almost random variation of arc parameters influences significantly the arc performance during single-phase autoreclosure on transmission lines. Depending on the variation of arc parameters, certain effects of interaction with the transmission system are observed. In this relation, field tests on real overhead lines are extremely useful to verify numerical arc simulations and to understand the arcing phenomenon. Authors have participated in the past in several field tests performed on a 400 kV overhead line without shunt compensation and on 750 kV line with shunt compensation.
