A un réseau monophasé sont reliés, moyennant les bornes 1 et 2, les conducteurs 3 et 4 qui se terminent sur deux montages To a single-phase network are connected, through terminals 1 and 2, conductors 3 and 4 which end on two fixtures
en parallèle 5 et 6 réunis entre eux par le point de connexion 7. in parallel 5 and 6 joined together by the connection point 7.
Le montage 5 comprend un condensateur 8 d'env. 33 nF et un coupe-circuit en parallèle qui saute sous un courant d'environ The assembly 5 comprises a capacitor 8 of approx. 33 nF and a parallel circuit breaker that jumps under a current of about
1 A. Le deuxième montage 6 se compose du moteur synchrone 10 con- 1 A. The second assembly 6 consists of the synchronous motor 10 con-
çu pour une tension de 24 V et absorbant sous cette tension un courant d'env. 2,5 mA. Parallèlement à ce moteur 10 est montée une lampe luminescente 11 dont la tension d'allumage s'élève à for a voltage of 24 V and absorbing a current of approx. 2.5 mA. In parallel with this motor 10 is mounted a luminescent lamp 11 whose ignition voltage amounts to
env. 60 jusqu'à 70 V, mais n'a pas de résistance série. approx. 60 to 70 V, but has no series resistance.
Si aux bornes 1 et 2 est appliquée une tension de 24 V, le If terminals 1 and 2 have a voltage of 24 V, the
courant, inférieur à 1 A, traverse le coupe-circuit, le conden- current, less than 1 A, passes through the circuit breaker,
sateur 8 restant sans effet. Le point 7 se trouve donc sous la sator 8 remaining without effect. Point 7 is therefore under the

cente 11, vu la trop faible tension d'allumage, ne marche pas. 11, because of the low ignition voltage, does not work.
Si l'ensemble est alimenté par une tension alternative de 220 V, le point 7 se trouve aussi, au moment du branchement, If the set is powered by an alternating voltage of 220 V, the point 7 is also, at the time of connection,
sous cette tension, par suite du court-circuit du condensateur 8. under this voltage, as a result of the short circuit of the capacitor 8.
La tension d'allumage de la lampe 11 étant dépassée, la lampe s'allume et fait descendre le potentiel au point 7 par rapport au conducteur 2 jusqu'à la tension de marche d'env. Since the ignition voltage of the lamp 11 is exceeded, the lamp lights up and lowers the potential at point 7 with respect to the conductor 2 to the operating voltage of approx.
50 V. Il ne peut donc pas y avoir surcharge du moteur, mais le courant qui circule dans l'ensemble, dépasse 1 A, ce qui fait sauter le coupe-circuit 9. Le condensateur 8 agit donc comme résistance série, la tension de marche de la lampe luminescente chute et la lampe s'éteint. La capacité du condensateur est telle que le moteur se retrouve sous une tension d'env.50 V. There can therefore be no overload of the motor, but the current flowing in the assembly, exceeds 1 A, which makes breaker 9 jump. The capacitor 8 therefore acts as a series resistance, the voltage of the luminescent lamp falls and the lamp goes out. The capacity of the capacitor is such that the motor is under a voltage of approx.
24 V. Vu le coupe-circuit 9 sauté, on peut voir si l'ensemble a été alimenté en courant alternatif 24 V ou 220 V.24 V. Given circuit breaker 9 jumped, it can be seen if the assembly was supplied with 24 V or 220 V alternating current.
