Document Type and Number:
Japanese Patent JP6745286
Kind Code:
B2
Abstract:
The invention relates to a current transformer (1) comprising: a core carrier (3) having two electrically conductive carrier ends (9, 11) and at least one electrically conductive carrier tube (13) arranged between the two carrier ends (9, 11); multiple current transformer cores (5), wherein each current transformer core (5) runs in a ring shape on an outer side of the carrier tube (13) about a longitudinal axis of the carrier tube (13); and an electrically conductive current transformer casing (7) which surrounds the current transformer cores (5) and is securely connected to both carrier ends (9, 11). In addition, a first carrier end (9) is electrically insulated from each carrier tube (13) via an insulating element (15), and the second carrier end (11) is connected in an electrically conductive manner to each carrier tube (13).
