An operating mechanism for an electric switch assembly, the operating mechanism being adapted to be operationally connected to a first electric switch (71) and a second electric switch (72). The operating mechanism comprises a frame (2), an operating lever (12), a first link (4), a second link (6), a coupling system adapted to selectively couple the second link (6) to the first link (4), and an actuation system coupled to the first link (4) and the second link (6) for actuating an actuation lever (171) of the first electric switch (71) and an actuation lever (172) of the second electric switch (72). The actuation system comprises a first actuation protrusion (41) and a second actuation protrusion (42) stationarily connected to the first link (4), and a third actuation protrusion (63) and a fourth actuation protrusion (64) stationarily connected to the second link (6).

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 perform (110) a current injection into the neutral point of the three-phase electric network by using a frequency different from a frequency of the three-phase electric network, obtain (120) a value of a zero-sequence impedance of the three-phase electric network and/or obtain (120) a value of a zero-sequence admittance of the three-phase electric network, and determine (130), based on the obtained value of the zero-sequence impedance and/or based on the obtained value of the zero-sequence admittance, whether to initiate a tuning of the arc suppression device of the three-phase electric network.
