The aim of this study is the evealuation of the overvoltages due to the reactors switching. Precisely, the reactors will be connceted in transformers tertiary. Two cases will be considered: reactors connected to 400kV/220kV/24kV transformers at Itxaso and Villarino. Reignition process in the circuit breaker will be modeled. The sensitivity with respect to several parameters of the installation will be studied. The study will be addressed with the ATP version of the EMTP program.
