Questions

Question

buenas tardes
el transformador trifasico a monofónico 8KVA
que potencia tendría en monofasico tendría 8KW

Answer

Buenas tardes,

Un transformador de potencia 8kVA, le sirve para la conexión de una carga a la salida de unos 4,5kW. Siempre es necesario sobredimensionar el cálculo de la potencia del trafo en un 20% de la la carga máxima a la que tengan que ser sometidos, para garantizar el correcto funcionamiento del mismo.

Si quisiera conectarle una carga de 8kW necesitaría una potencia de unos 14kVA, nosotros disponemos del modelo de 16kVA

Question

Hola, me he comprado una finca que va en trifasico por la bomba del pozo, y estoy pensando en instalar un transformador trifasico a monofasico para poder alimentar la casa 8 ya que todo funciona en monofasico) , y me gustaria saber la eficiencia del transformador, se pierde algo transformando el trifasico en monofasico? o seria mas conveniente hacer una instalacion de "tres monofases" en la casa? Muchas gracias por la pregunta.

Answer

Buenos días,

Podría utilizar sin problema un trafo para pasar de trifásico a monofásico, lo que hay que tener en cuenta es el consumo que va a tener para poder calcular correctamente la potencia del trafo adecuado a sus necesidades, teniendo en cuenta que el cálculo del mismo debe de hacerse con un sobredimensionamiento del mismo para un correcto funcionamiento y evitara así el deterioro del equipo.
