Abstract

A system (1) for enabling transmittal of high voltage electric power from a towing vehicle (2) to a trailer vehicle (3), the towing vehicle (2) comprising: a source of high voltage electric power (4); a cable connector (5) configured to be connected to a first end connector (6a) of a cable (6) that comprises i) at least one power cord (21, 22, 23), ii) a protective earth conductor (25), and iii) one or more signal cables (26, 27) configured to transmit a signal or message that indicates that the cable (6) is connected; a cable interface unit (7) configured to receive and process the signal or message that indicates that the cable (6) is connected to the cable connector (5), wherein the cable interface unit (7) is configured to measure electric insulation between the at least one power cord (21, 22, 23) and the protective earth conductor (25) so as to allow for checking insulation capability of the cable (6) before applying high voltage to the cable (6).
