    SEPAM Trip Curves: Type 1 versus Type 1.2

    Issue
    User would like to understand the different tripping characteristics between Type 1 and Type 1.2 trip curves on the SEPAM relays

    Product Line
    SEPAM series 20
    SEPAM series 40
    SEPAM series 80

    Environment
    SFT2841

    Resolution
    There are two types of curves that can be selected for a SEPAM relay. These curve types are Type 1 and Type 1.2. The curve descriptions and curve type are outlined in the table below.


    The tripping behavior of Type 1 curves can be found at FA289661. There are calculators available at this FA for SEPAM and MiCOM trip curves. Type 1 trip curves pick up when the measured current equals the threshold current setting on the relay (I = Is).

    Type 1.2 trip curves pick up when the measured current equals the threshold current setting of the relay multiplied by 1.2 (I = 1.2*Is). Aside from the pickup, the Type 1.2 curve follows the same tripping characteristics as a Type 1 IEC curve. 

    Please refer to image below for a comparison of Type 1 and Type 1.2 tripping characteristics.
