Необходимые параметры силового трансформатора, требуемые для выбора и расчета его защиты

Abstract

Рассмотрены необходимые параметры силового трансформатора, которые требуются для расчета его защиты, исследованы трансформаторы с различным номинальным напряжением как масляные, так и сухие. В основу методики положено способы расчетов необходимых параметров релейной защиты трансформаторов с различными схемами и группами соединений обмоток.

Considered necessary parameters of power transformer that is required to calculate its protection, investigated transformers with different nominal voltage as oil and dry. The methodology put methods of calculations required relay protection settings of transformers with different schemes and groups of winding connections.
