Directional 67/67–TOC Elements (phases)
The dynamic pickup values and time delays associated with directional overcurrent phase protection are set at
address block 20
The dynamic pickup and delay settings for the 67-2 high-set element are set at addresses 2001 67c-2
PICKUP and 2002 67c-2 DELAY respectively; the dynamic pickup and delay settings for the 67-1 element are
set at addresses 2003 67c-1 PICKUP and 2004 67c-1 DELAY respectively; and the pickup, time multiplier
(for IEC curves or user-defined curves), and time dial (for ANSI curves) settings for the 67-TOC element are
set at addresses 2005 67c-TOC PICKUP, 2006 67c-TOC T-DIAL, 2007 67c-TOC T-DIAL respectively.
Directional 67/67N Elements (ground)
The dynamic pickup values and time delays associated with directional overcurrent ground protection are set
at address block 21:
The dynamic pickup and delay settings for the 67N-2 high-set element are set at addresses 2101 67Nc-2
PICKUP and 2102 67Nc-2 DELAY respectively; the dynamic pickup and delay settings for the 67N-1 element
are set at addresses 2103 67Nc-1 PICKUP and 2104 67Nc-1 DELAY respectively; and the pickup, time mul-
tiplier (for IEC curves or user-defined curves), and time dial (for ANSI curves) settings for the 67N-TOC element
are set at addresses 2105 67Nc-TOC PICKUP, 2106 67Nc-TOC T-DIAL, 2107 67Nc-TOC T-DIAL respec-
tively.
2.4.3 Settings
The table indicates region-specific default settings. Column C (configuration) indicates the corresponding sec-
ondary nominal current of the current transformer.
