50P/67P - DEFT Overcurrent Protection
Available Elements
50P[1] ,50P[2] ,50P[3]
If using inrush blockings, the tripping delay of the current protection functions must be
at least 30 ms or more in order to prevent faulty trippings (applies only to devices
which are equipped with Inrush protection)..
All overcurrent protective elements are identically structured.
All ANSI 67 elements (directional overcurrent protection), will be displayed
as ANSI 50 elements. That means, that the name of an ANSI 50 element
wont change, if it is set within the device planning from “non-directional” to
“directional”.
For each element the following characteristic is available:
•DEFT (definite time).
Explanation
This element offers a criterion setting. The criterion setting tells if the threshold is based on the fundamental (Phasor)
or RMS.
For Tripping curves, please refer to “Instantaneous Current Curves (Phase)” located in the Appendix.
