\u2160 : Comment tester la r\u00e9sistance de l'enroulement d'un transformateur ?<\/strong><\/p>\n\n\n\n

R\u00e9sistance du bobinage du transformateur<\/strong> sont obtenues en faisant passer un courant continu connu dans l'enroulement test\u00e9 et en mesurant la chute de tension \u00e0 chaque borne (loi d'Ohm).<\/p>\n\n\n\n

La r\u00e9sistance de l'enroulement des transformateurs varie en raison de spires court-circuit\u00e9es, de connexions desserr\u00e9es ou de contacts d\u00e9t\u00e9rior\u00e9s dans les changeurs de prises. Quelle que soit la configuration, les mesures de r\u00e9sistance sont normalement effectu\u00e9es phase par phase et les relev\u00e9s sont compar\u00e9s entre eux pour d\u00e9terminer s'ils sont acceptables.<\/p>\n\n\n\n

\u2161 : Quelle est la m\u00e9thode utilis\u00e9e pour mesurer la r\u00e9sistance d'un enroulement ?<\/strong><\/p>\n\n\n\n

La r\u00e9sistance des enroulements peut \u00eatre mesur\u00e9e directement \u00e0 l'aide d'un ohmm\u00e8tre. Une autre m\u00e9thode consiste \u00e0 calculer la r\u00e9sistance en mesurant le courant traversant chaque enroulement, \u00e0 l'aide d'un amp\u00e8rem\u00e8tre A, lorsqu'une tension est appliqu\u00e9e et mesur\u00e9e \u00e0 l'aide d'un voltm\u00e8tre V.<\/p>\n\n\n\n
