Zusammenfassung:The invention relates to a testing apparatus (1) and a method for detecting insulation resistance (R) of an unshielded high voltage line (2), wherein the testing apparatus (1) comprises: a voltage source (4) for providing a measurement voltage (U) for the high voltage line (2); an accommodating device (5) for accommodating the high voltage line (2) and for connecting the high voltage line (2) to the voltage source (4); an insulation tester (7) for detecting the insulation resistance (R) on the basis of the measurement of a leakage current via the insulating sheath (3); two electrically conductive half shells (HS1, HS2) which, when combined, form hollow cylindrical sheathing (8) for the high voltage line (2); and two contact probes (T1, T2, T3) which can be electrically connected to the sheathing (8) and to an inner conductor (L1, L2) of the high voltage line (2), wherein the insulation tester (7) is designed to measure a current between the contact probes (T1, T2, T3) as the leakage current. 本发明涉及用于检测未经屏蔽的高压线
