ABSTRACT:
A voltage sag generator device for use in an electrical generator machine such as a wind turbine, connected to an electrical network including one to three parallel transformers connected on one side to the wind turbine via a coupling switch and circuit breakers, and earthed on the other side via circuit breakers and a control switch. The device includes mechanisms for causing short-circuits when the coupling switch and the control switch are actuated in such a way that a voltage sag having the required duration and type is generated, and mechanisms for protecting the transformers during voltage sag generation.
