High voltage transformer, method for producing a high voltage transformer and test system and test signal device comprising a high voltage transformer

A high-voltage transformer,

• wherein the high-voltage transformer is designed as a toroidal transformer and comprises:
• a magnetizable core;
• a low-voltage winding, which is arranged around the magnetizable core;
• a high-voltage winding, which is arranged around the magnetizable core and is electrically insulated from the low-voltage winding,
• the high-voltage winding being embodied at least partially as a pilgrim step winding;
• and
• a protective layer, arranged between the high-voltage winding and the low-voltage winding,
• the protective layer being configured such that it electrically insulates the high-voltage winding and the low-voltage winding from one other,
• the protective layer comprising an electrically conductive layer for shielding the high-voltage winding from the low-voltage winding,
• the high-voltage winding being arranged concentrically around the magnetizable core, the protective layer being arranged concentrically around the high-voltage winding, and the low-voltage winding being arranged concentrically around the protective layer, and
• the protective layer comprising a first electrically insulating layer adjacent to the high-voltage winding, a second electrically insulating layer adjacent to the low-voltage winding, and the electrically conductive layer disposed between the first electrically insulating layer and the second electrically insulating layer.
