CURRENT SENSOR CONSISTING OF A CABLE FOR ATTACHMENT IN THE FORM OF A LOOP

The sensor comprises a cable (5) looped around an element to be monitored, and includes a winding (10) on the Rogowski principle. It is original in that it is open at its ends (6, 7), that is to say the winding (10) is flush with the end faces (25) of the cable (5), and perfect continuity of the win...

Zusammenfassung:The sensor comprises a cable (5) looped around an element to be monitored, and includes a winding (10) on the Rogowski principle. It is original in that it is open at its ends (6, 7), that is to say the winding (10) is flush with the end faces (25) of the cable (5), and perfect continuity of the winding and of measurement over a circumference is established by abutting the two ends together. This cable may have a temperature sensor and a memory in which the measurement characteristics of the sensor are held. The sensor is reliable and accurate, and it can be left permanently in an electrical apparatus, or replaced, with no difficulty.
