Пристрій для контролю вводів із внутрішньою ізоляцією конденсаторного типу силового трансформатора

Abstract

Device for control of inputs with inner insulation of capacitor type of a power transformer includes voltage sensors, sensor of frequency of network voltage, blocks for setting capacity of the inner insulation of phase inputs, block for setting maximal permitted current, and arithmetical-logical block by means of which one determines absence or presence of defect of insulation of transformer inputs and carries out control of current in phases.
