Transformador, se pueden sumar los VA manteniendo voltaje

I. Hola Roberto, aunque no conozco la respuesta tuve la fortuna de ver un poco de información sobre este tema, ojalá pueda serle de alguna utilidad mientras le atiende un profesional o experto de primera mano.

Le ruego me disculpe por las molestias de lectura y la forma de responderle. Ánimo.
