Cómo se calcula el área de la formaleta o carretel para un transformador de 380v a una salida de carga de 220v 2amperes o sea estrella- triángulo, es para un variador de frecuencia, Gracias
Depende de la aplicación, pero puede estar en estrella o en triángulo indistintamente. Por ejemplo, para transformadores de distribución MT/BT, la conexión más típica suele ser triángulo en el primario y estrella en el secundario

Excelente video! Muchas gracias por la dedicación.
Cómo se calcula el área de la formaleta o carretel para un transformador de 380v a una salida de carga de 220v 2amperes o sea estrella- triángulo, es para un variador de frecuencia, Gracias
Muchas gracias por tus vídeos...
Explicado de una manera muy sencilla, me ayudas mucho en mis estudios, sigue así. Excelentes vídeos.
Q buen video.tengo una pregunta ? Cuál sería la conexión general del devanado primario? Gracias
Depende de la aplicación, pero puede estar en estrella o en triángulo indistintamente. Por ejemplo, para transformadores de distribución MT/BT, la conexión más típica suele ser triángulo en el primario y estrella en el secundario
