Questions

Question
Buenos dias: Tengo una instalación solar. Y la entrada de la Red es muy irregular y la compañía no hace caso. ,¿Sirve para regular la entrada de la Red Y también cuando hay excedentes de la instalación solar puede volcar la electricidad por el autotransformador? Saludos Jorge Fernández Telefono 670815013
Answer
Buenso días.
 
Con un autotransformador lo único que consigue es hacer un cambio de tensión, trifásica 230 / trifásica 400 Vac o viceversa.
 
Los estabilizadores de tensión monofásicos o trifásicos, no son bidireccionales.

Question
Le neutre est-il commun au primaire et au secondaire? C'est un couplage Ynyn? Merci
Answer

Bonsoir,

Le neutre est généré en sortie, le neutre est généré en transformant la valeur en tension de sortie. Si l'entrée est de 230V, la sortie est de 400V+N, et si l'entrée est de 400V, la sortie est de 230V+N.

La configuration est étoile-étoile

Question
Hola quería consultar si conecto el autotransformador a un generador trifásico de imanes permanentes con 3fase a 230v y2200kw que puedo tener a conectarse a autotransformador reversible gracias
Answer

Buenos días,

Si es posible usar un autotransformador, tiene usted que instalar las protecciones (Magnetotermicos) adecuados entre el generador y autotransformador.

Saludos
