Abstract (en)
[origin: EP0571319A2] In the case of the current transformer according to the invention, the components which are used are arranged in a novel manner. The primary winding (7) is arranged around the secondary winding (8), with the extended core (9), at a distance which is provided for the insertion of high-voltage insulation (10). The secondary winding (8) and core (9) are located in an earthed electrically conductive tube (12) in which the output leads of the secondary winding are connected to earth. This construction avoids the mutual looping around of the core and windings which is necessary according to the prior art and which, for some applications, is unfavourable and costly in production engineering terms. <IMAGE>
