Zusammenfassung:A method for controlling switchgear includes the implementation of a limitation of the intensity value of the power supply current of a coil of an actuator, including acquisition of a power supply current limit value; generation of a reference value representative of the power supply current limit value; acquisition of a signal representative of the intensity of the power supply current circulating through the coil; comparison of the reference signal with the signal representative of the intensity of the power supply current; inhibition of the current power supply of the coil, as long as the intensity of the power supply current has a value greater than or equal to the reference value, the current power supply of the coil being re-established when the intensity of the power supply current returns below the reference value.
