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
