  • Patent number: 9714974
    Abstract: Disclosed is a device for detecting an open phase of a connection line of a standby transformer in a nuclear power plant by using a Rogowski coil. A Rogowski coil is provided to a neutral line of a Y connection at the primary side of the standby transformer. An open phase detection unit is provided for determining the generation of an open phase at the primary side and generating a warning signal if a current induced in the Rogowski coil is maintained at a value higher than a preset reference value for a time longer than a preset reference time in a state where a circuit breaker at the secondary side of the standby transformer is open. A main control unit is provided for displaying the warning to an administrator according to the warning signal provided by the open phase detection part.
