Abstract
NUCLEO LAMINADO PARA UN TRANSFORMADOR MONOFASICO O TRIFASICO. EN EL CASO DE UN TRANSFORMADOR MONOFASICO, EL NUCLEO SE CARACTERIZA PORQUE UNA PARTE DE LAS CAPAS DE LAMINAS QUE COMPONEN DICHO NUCLEO CONSTAN DE ALAS HECHAS DE CHAPA DE ACERO AL SILICIO DE GRANO ALTAMENTE ORIENTADO Y DE YUGOS HECHOS DE CHAPA DE ACERO AL SILICIO DE GRANO CON ORIENTACION RELATIVAMENTE BAJA. EN EL CASO DE UN TRANSFORMADOR TRIFASICO, EL NUCLEO SE CARACTERIZA PORQUE TODAS LAS CAPAS DE LAMINAS QUE COMPONEN DICHO NUCLEO CONSTAN DE ALAS HECHAS DE CHAPA DE ACERO AL SILICIO DE GRANO ALTAMENTE ORIENTADO.
