A measuring device is detachably connected between the vehicle traction voltage system and the high voltage appliance. The measuring device includes a first and second terminal configured to receive a first and second probe of a voltage measuring instrument, a first and second resistor arranged to connect each terminal, upon the measuring device being attached to the vehicle voltage traction system, to a first and second traction voltage conductor of the traction voltage system extending through the measuring device. The measuring device, upon the measuring device being attached to the vehicle voltage traction system, connects to a Hazardous Voltage Interlock Loop of the vehicle extending through the measuring device so that the HVIL is broken when the measuring device is detached from the traction voltage system, thereby inactivating the traction voltage system.
