Abstract

An arrangement for the contact-less testing for the presence of an electrical voltage in an electrical conductor or component. The arrangement comprises a sensor device (21), exhibiting an electrical conductor of a specified length, one end (22) of which is open, a first amplifier stage (24), to the input of which the opposite end (31) of the sensor device is connected, and a second amplifier stage (26), the input (32) of which is connected to the output (25) from the first amplifier stage. The second amplifier stage exhibits an indicator device (20) which, when an electric current is induced through the sensor device, will indicate the presence of an electrical voltage in the aforementioned component within a specified sensing area in the vicinity of the sensing device.
