METHOD FOR CONTROLLING A CURRENT-INTERRUPTING DEVICE IN A HIGH-VOLTAGE ELECTRICAL NETWORK

摘要

The invention relates to a method of controlling switchgear in order to estimate the remanent flux value of a power transformer during disconnection from a high-voltage electrical network using voltage measurements delivered by a capacitive voltage transformer by correcting the transfer function of the capacitive voltage transformer, and in which said value is delivered to a controller that determines the optimum switchgear switching instant.
