The user can select thetimer characteristics with the Operating curve type and Type of reset curve settings.When the DT characteristic is selected, it is only affected by the Operate delaytime and Reset delay time settings.The IED provides 16 IDMT characteristics curves, of which seven comply with theIEEE C37.112 and six with the IEC 60255-3 standard. Two curves follow thespecial characteristics of ABB praxis and are referred to as RI and RD. In additionto this, a user programmable curve can be used if none of the standard curves areapplicable. The user can choose the DT characteristic by selecting the Operatingcurve type values "ANSI Def. Time" or "IEC Def. Time". The functionality isidentical in both cases.The following characteristics, which comply with the list in the IEC 61850-7-4specification, indicate the characteristics supported by different stages:Table 266:Timer characteristics supported by different stagesOperating curve type Supported byEFLPTOC EFHPTOC(1) ANSI Extremely Inverse x x(2) ANSI Very Inverse x(3) ANSI Normal Inverse x x(4) ANSI Moderately Inverse x(5) ANSI Definite Time x x(6) Long Time ExtremelyInversex(7) Long Time Very Inverse x(8) Long Time Inverse x(9) IEC Normal Inverse x x(10) IEC Very Inverse x x(11) IEC Inverse xTable continues on next pageSection 4 1YHT530004D05 DProtection functions266 615 seriesTechnical Manual
