Dimensions should suffer »if possible, linleiterstroiawandl ^ a * is used even with a very small 3 _? as long as the required secondary power can just be achieved * If the latter is not possible »you have to install a winding current transformer. These requirements can only be met with difficulty or only in individual cases by special designs with the curved current transformers known up to now, because the current transformers are usually significantly wider than the smallest permissible distance between the phase conductors.

Firing refers to winding current converters with a single-window, preferably ring-shaped iron core supporting the secondary winding and the primary winding . an insulating housing, which meet the various requirements mentioned above * according to the fire, this is achieved by the fact that the primary connecting pieces, which simultaneously serve as the support for the entire transducer, are formed as pieces of metal inserted into the core window opening from both sides or as straight-angled flat rails, their legs lie in an Ibe & e or * in a vertical plane on the core plane or in a plane running perpendicular to the bed surface of the hanging core, to which the insulating housings are attached in this way. " that they only protrude slightly beyond the side surfaces of the insulating housing, which are parallel to the central plane of the lowering element. "Am such a winding current transformer
