Abstract
A device for identifying contact with an electrical conductor by at least one electrically conductive tool (2ra, 2rb). The device comprises a tool holder (Ir) rotationally mounted about a rotation axis (X), and the tool (2ra, 2rb) arranged on the tool holder. The device additionally comprises an electrically conductive body (ECB) and a rotor-side inductive element (L1) arranged on the electrically conductive body (Ir). A parallel resonant circuit comprises at least one rotor-side circuit element (A), at least one stator-side circuit element (B), a stationary circuit arrangement (28) and a stator-side inductive element (L2). The rotor-side inductive element and the stator-side inductive element are arranged to measure characteristic oscillation parameters (φ, Am, f) of the parallel resonant circuit independently of the rotation speed of the tool holder (Ir). An insulation-stripping machine and a method for identifying contact with an electrical conductor by at least one electrically conductive tool as disclosed.
