Beschreibung
Zusammenfassung:	The invention relates to a high-voltage column current transformer (1) comprising a column insulating body (3) and a head (2) arranged thereon, whereby the head (2) defines a volume (6) and comprises arranged therein a primary winding conductor (7), a secondary winding core assembly (5) having secondary winding leads (4) and a conical insulator spacer (9) having a base (10) and an apex (11) with a lateral face (12) therebetween, the conical insulator spacer (9) is arranged with its base (10) on a bottom of the head (2) facing the column insulating body (3) and its apex (11) holds the secondary winding core assembly (5) distant from the head (2), and the conical insulator spacer (9) comprises at least one electrode (13) embedded in the base (10) and/or the apex (11), and/or the conical insulator spacer (9) comprises at least one opening (15) in the lateral face (12).
