  • Human-machine interface for a self-supplied relay
    Patent number: 9818565
    Abstract: A design of a protection relay, and interface with an operator of a protection relay, are disclosed. The protection relay can include a base relay for measurement of line current and for generation of a trip signal, a base Human Machine Interface (HMI) for user specifying of a base setting of an operating parameter of the protection relay, and an optionally active Human Machine Interface (HMI) unit having a processing unit to manage plural activities with controlled power consumption.
    Type: Grant

  • Dip switch change detection in a self powered relay
    Patent number: 9455563
    Abstract: An interface is disclosed for a self powered protection relay that uses mechanical switches for its configuration. The protection relay can include a base relay for measurement of line current and for generation of a trip signal, and a Human Machine Interface (HMI) unit for specifying, by a user, a base setting of an operating parameter of the protection relay. The base relay can be self-powered from the line and the HMI unit can include an auxiliary power supply. The protection relay is configured with mechanical switches provided in the protection relay. The HMI unit in the protection relay is designed to detect and alert the user of the relay of any change in the base setting carried out with one or more mechanical switches provided in the relay in powered and unpowered conditions of the base relay.
