摘要： L'invention porte sur un procédé de localisation d'un défaut affectant une phase d'un départ en défaut d'un réseau de distribution électrique, comprenant les étapes suivantes :
- obtention d'un signal électrique au moment du défaut, le signal électrique étant mesuré (MES) à un poste source (PS) du réseau uniquement pour le départ en défaut ;
- examen de tronçons (TR1, TR2, TR3, TR4, TRn) du départ en défaut, chaque tronçon ayant une tête et une queue et l'examen d'un tronçon comprenant :
o à partir du signal électrique obtenu, l'estimation d'un courant de défaut au niveau de la queue du tronçon et le calcul d'une distance du défaut depuis la tête du tronçon ;
o le calcul d'un écart entre la distance estimée et une longueur séparant la tête de la queue du tronçon et ;
o en fonction dudit écart, l'identification ou non d'une solution de localisation du défaut.

摘要： The invention relates to a method for the detection and/or measurement of fouling in a heat exchanger, whereby the resistance value (R
1 , R
2 ) of a resistor (R), placed on a wall (P) of this heat exchanger, is measured at two different instants and a value of the measurements (R
2 ; R
1 ) that corresponds to a function of the values measured at these two instants is determined, characterized in that the resistor (R) is subjected in succession to two power levels (P
1 , P
2 ) that are each maintained for a certain duration, the first power level (P
1 ) being below the second power level (P
2 ), and the measurements of the two resistance values (R
1 , R
2 ) being respectively carried out during application of these two power levels. The invention also relates to a device for the detection and/or measurement of fouling in a heat exchanger, characterized in that it includes a resistor (R), placed on a wall (P) of this heat exchanger, means (16) for delivering a constant power to said resistor (R) and processing means (17), these various means being capable of implementing the method according to the invention. Finally, the invention relates to the use of said method or of said device.

摘要： The invention relates to a belt for measuring physical quantities of an object, including at least one measuring sensor (5), a strap (10) and a device for tightening the strap around the object. According to the invention, the belt includes a device (50) for pressing the measuring sensor (5) in a first direction (55) towards the object, including a casing (53) fastened to the strap (10), an intermediate part (52) and a stress member (51) designed to make the intermediate part (52) take a lowered first position in which it presses towards the sensor (5) in the first direction (55), and a raising member (54) for holding the intermediate part (52) in a raised second position above the first position, against the action of the stress member (51), the raising member (54) being actuatable from the exterior of the casing (53) in order to make the intermediate part (52) pass from the raised second position to the lowered first position in which it presses towards the sensor (5).

摘要： The invention relates to a belt for measuring the temperature of an object, the belt including: at least one temperature sensor (5); a strap (10) having a circumference intended to encircle the object; and a device (20) for tightening the strap (10) around the object, characterized in that the temperature sensor (5) is mounted on an individual thermally insulating carrier (6) that is guided in a guiding direction (62) toward the object (OBJ) between at least two thermally insulating runners (31, 32) that bear against the object, the runners (31, 32) being fastened to the strap (10).
