Abstract
A method for operating a medium voltage circuit breaker or recloser comprising at least one electric pole, each including a movable contact and a fixed contact, being in a closed or an open position after switching operations of the medium voltage circuit breaker or recloser, and an electromagnetic actuator, includes: monitoring a travel curve of the movable contact, the travel curve being derived by an evaluation of a shape of an applied current and a shape of an applied voltage using a mathematical representation of the electromagnetic actuator.
