A case of abnormal overvoltages in a Petersen grounded 132-kV system caused by broken conductor.

This paper analyzes a case where a broken phase conductor in a Petersen grounded system caused extensive damage and outages due to excessive stationary overvoltages. It is shown that the high overvoltages resulted from a combination of the following: (1) the fault occurred on a radial connection, (2...
