<p>Control apparatus for the starting of a high-voltage alter-nating-current motor (M1) with a voltage rating of at least 3 kV, the electric power supply to said motor being implemented using a transformer (T1) that raises the voltage of a low-voltage, at most 1-kV three-phase voltage source, such as a supply network, to produce a high voltage feeding the motor. The control apparatus is a low-voltage system connected before the transformer, the starting of the motor being controlled via the transformer from the low-voltage source.</p> |
