  • Patent number: 9502187
    Abstract: 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.
    Type: Grant

  • Patent number: 7336461
    Abstract: A method for determining the reclose time of a circuit breaker on a three-phase high-voltage electric network after separation of contacts 7A, 8A, 7B, 8B, 7C, 8C in the presence of a fault on one of the three phases A, B or C includes measuring voltages ULA0, ULBO and ULCO, measuring voltage USAO,determining the voltage USA0, USB0, and USCO, calculating the differences ULAB, ULAC and ULBC, calculating the differences USAB, USAC, and USBC. From these measurements and calculations, a determination of the reclose time is made on the basis of the voltage differences.
