摘要： The invention relates to a high voltage transformer (6) having a sensor system (30) for monitoring physical characteristic variables. In particular, said sensor system has at least one sensor (1) that comprises a glass fiber (3) with a sensor head (2). Said sensor head supports a plurality of Bragg gratings (7, 8, 9). An evaluation unit (10) is associated with the sensor system and is connected to the at least one sensor head via said glass fiber. The invention is based on the general inventive concept of arranging the sensors of the sensor system between successive windings (4, 5) of the high voltage transformer using spacers. In addition, the use of a plurality of Bragg gratings in the sensor head ensures that at least one of the Bragg gratings determines the actual physical characteristic variables such as temperature or contact force (A).

摘要： A current limiting device (10) is formed from a transformer comprising an element made from a magnetothermal material (20), a primary conductor (12) and a secondary winding (16). Heat is generated by the current flowing through the primary conductor (12) and when said current exceeds a certain threshold it modifies the coupling coefficient of the transformer (10), which makes it possible to limit the current in the primary conductor (12).

摘要： Techniques for improving performance of a transformer shared amongst a plurality of operating modes. In an aspect, first and second primary windings of a transformer are coupled to an AC ground voltage. Primary windings are mutually coupled to a secondary winding of the transformer. To render the second primary winding inactive, e.g., when operating in a first mode, a switch coupling the second primary winding to the common reference voltage is opened. Similarly, when it is desired to render the first primary winding inactive, e.g., when operating in a second mode, a switch coupling the first primary winding to the common reference voltage is opened. In this manner, the inactive primary winding advantageously does not load the secondary winding. Further aspects provide for, e.g., extending the techniques to more than two modes, and alternative techniques to mutually couple the signal from the primary to the secondary winding.
摘要翻译：用于改善在多个操作模式之间共享的变压器性能的技术。在一个方面，变压器的第一和第二初级绕组耦合到AC接地电压。初级绕组相互耦合到变压器的次级绕组。为了使第二初级绕组无效，例如当以第一模式操作时，将第二初级绕组耦合到公共参考电压的开关断开。类似地，当期望使第一初级绕组无效时，例如当在第二模式下操作时，将第一初级绕组耦合到公共参考电压的开关被打开。以这种方式，无源初级绕组有利地不加载次级绕组。另外的方面提供了例如将技术扩展到多于两种模式，以及将信号从初级绕组相互耦合到次级绕组的替代技术。
