1. A protection adapter for an overvoltage protection of an electrical operating device in a high-voltage line, the protection adapter comprising:
a first adapter interface for electrically conductively coupling the protection adapter to an open-air interface of the high-voltage line;
a second adapter interface for electrically conductively coupling the protection adapter to an operating-device interface of the electrical operating device;
a connecting line for electrically conductively coupling said first adapter interface and said second adapter interface; and
an electrically insulating insulation sheath surrounding at least said connecting line; and
the protection adapter having a surge impedance configured for reducing electrical surges from the high-voltage line, said surge impedance having a surge impedance profile with an increasing form or a decreasing form at least in areas thereof.
