The device for measuring alternating current in high-voltage circuits contains a transmitter of the measured signal, connected to the measurement circuit, containing a current sensor coupled with a measuring converter and a power pack. The device is also equipped with a receiver of the measured signal, located at the ground level potential. Characterized in that: The infrared transmitter (5), coupled coaxially with one end of the insulator (2), is the transmitter of the measured signal. The patent opening in the insulator constitutes the route of the measurement signal transmitted by the infrared transmitter (5). The infrared detector (8) is the signal receiver. It is coaxially coupled with the other end of the insulator (2) and connected to the electronic receiving system (9). |
