Title: METHOD FOR MANUFACTURING A MEASUREMENT SENSOR FOR A CIRCUIT BREAKER
Abstract:
- 15 - ABSTRACT *************** Method for manufacturing a measurement sensor for a circuit breaker The subject of the present invention is a method for manufacturing a measurement sensor (10), a measurement sensor manufactured using said method, a circuit breaker comprising such a measurement sensor (10) and a method for controlling such a circuit breaker (100). The measurement sensor (10) comprises at least one current measurement unit (12) comprising a torus through which a main conductor (R, S, T, N) is able to pass, and a first conductor wound around the torus, a current transformer (14) through which the main conductor (R, S, T, N) passes and a data management unit (18). The measurement sensor (10) comprises a voltage measurement unit (16) linked to the main conductor (R, S, T, N) to measure a potential in the main conductor (R, S, T, N). - Fig. 1 -
