    Presentation

    IRIPRO Series offers a compact Over-current protection solution for distribution/feeder segment. IRIPRO Family of protective relays are numeric relays that provides protection and monitoring with reliable and fast protection solution in a single unit with programmable digital outputs. The IRIPRO-V3 relays have been designed for controlling, protecting and monitoring industrial, utility distribution networks and substations. They can also be used as part of backup protection scheme for feeders, transformers and generators.

    Protection Function

    Three Phase Over-current Protection (50/51): The independent two stages are available for phase fault protection. For first stage (l>) the user may independently select definite time delay or inverse time delay with different type of curves. The second Hi-Set stage (l>>) can be configured with definite time only.
    Earth Fault Protection (50N/51 N): The independent two stages are available for earth fault protection. For first stage (le>) the user can select definite time delay or inverse time delay with different type of curves. The second Hi—Set (le>>) stage can be configured with definite time only.
    Relay Latching (86): Flelay can be configured to Latch /Unlatch depending on configuration. (Latching is possible in presence ofAuxiliary supply voltage only).
    Circuit Breaker Failure Protection (50 BF): The CB Failure Protection is based on supervision of phase and earth currents after tripping events. The test criterion is whether all phase currents have dropped to less than 5% of In within tCBFP. If one or more of the phase currents have not dropped to specified current within this time, CB failure is detected and the assigned output relay is activated.
    Reset Delay: This parameter introduces a delay in opening of relay contacts, when the current goes below the drop out value for over current, short circuit and earth faults. This parameter will not work when manual reset mode is selected.
