Abstract

A method and apparatus for controlling an arc suppression device of a three-phase electric network, the arc suppression device having an adjustable admittance connected between a neutral point of the three-phase electric network and earth, the apparatus being configured to determine (110) a resonant frequency of a zero-sequence system of the three-phase electric network and determine (120), based on the determined resonant frequency of the zero-sequence system of the three-phase electric network, whether to initiate a tuning of the arc suppression device of the three-phase electric network.
