Abstract
The invention relates to a high-voltage transformer whose primary and secondary winding connections 2, 3 are each passed via bushings 4, 5 to outer connecting points 6, 7, measurement means 10, 11, 12 being provided to determine the current intensity on the primary side and secondary side, which measurement means 10, 11, 12 are allocated to an evaluation device 12 in such a manner that, if the ratio of the current intensities does not correspond to the reciprocal of the transformation ratio of the transformer, the discrepancy is used to trip power circuit breakers 8, 9. In order to improve the safety of the high-voltage transformer and to simplify its construction, it is provided according to the invention that the means for determining the current intensities are two electrooptical current sensors 10, 11 which are each arranged in that region of the bushings 4, 5 which is adjacent to the outer connecting points 6, 7, the output signal of the respective electrooptical current sensor 10, 11 being capable of transmission into the evaluation device 12 by means of optical fibres (light guides) 14, 15. <IMAGE>
