Abstract
Se proporciona una protección diferencial de transformadores al medir una pluralidad de corrientes que corresponden a un primer conjunto de bobinas y a un segundo conjunto de bobinas de un transformador, compensar las corrientes con base a sus flujos respectivos a través de ya sea el primer conjunto de bobinas o el segundo conjunto de bobinas. Las corrientes compensadas se pueden aumentar intencionalmente para compensar las condiciones de irrupción magnetizante y/o sobreexcitación estacionaria asociadas con el transformador. El aumento con base en la sobreexcitación estacionaria, por ejemplo, se puede basar en ya sea la restricción armónica o una adición de una relación V/Hz a una señal de restricción. Se calcula una relación de corriente compleja que corresponde a la pluralidad de corrientes compensadas. La relación de corriente compleja se puede basar en un aparato de energía equivalente de dos terminales. Después, se aplica un análisis del plano alfa a la relación de corriente compleja. Con base en el análisis del plano alfa, un aparato de energía que incluye el transformador se desconecta selectivamente.
