The use of cooling-factor curves for coordinating fuses and reclosers

Abstract: This paper describes how to precisely coordinate distribution feeder automatic-circuit reclosers using cooling-factor data that accounts for the heating and cooling of source-side or loadside fuses throughout the recloser's operating sequence. This method yields results that are more accurate than other coordination methods commonly employed. Different coordination methods are discussed in this paper and the results are compared.

“…An adjustment of the fuse time-current characteristic is therefore needed. A more advanced model have been also implemented to account for the thermal response of a fuse during multiple reclosing operations using the coordination principles between fuses and reclosers presented in [28]. The features of this fuse model are detailed in reference [23].…”

“…Así se garantiza que aún en el caso de faltas permanentes con baja corriente de falta el fusible tenga suficiente tiempo de actuación antes de que opere el reconectador. Esta es una forma muy conservadora de hacer la coordinación, ya que los tiempos de espera para la reconexión programados al reconectador permiten que el fusible se enfríe y por tanto la curva de mínima fusión se parezca más a la de ensayo en laboratorio [68,69]. Las consignas de los relés se muestran en la Tabla.…”
