P14D Chapter 6 - Current Protection Functions
Example
If the overcurrent device has a setting of 160% In, but the minimum fault current for the remote fault condition is
only 80% In, then the required k factor is given by:
0 8
.
k = =
0 42 .
×
1 6 1 2
. .
The voltage threshold, Vdep OC V< setting would be set below the lowest system voltage that may occur under
normal system operating conditions, whilst ensuring correct detection of the remote fault.
