Zusammenfassung:The high-voltage electrical equipment of the invention has means for limiting the magnetising current which arises when a transformer is energised, upon re-establishing a system when the voltage suddenly increases after having isolated a fault or when two transformers are energised in parallel, as well as connecting/disconnecting the equipment from the electric power distribution network or selecting the number of coils of a primary winding in order to obtain the adjustment of the voltage in a secondary winding, for which it mainly has a tank (3) inside of which it has a dielectric medium (4) and a device (2) for limiting the magnetising current that in turn has at least one operating position (5, 6, 7, 8, 9, 10, 29) per phase, at least one operating medium (11, 12) per phase, and at least one first switching current limiting element (17) per phase.
