Coordination with DISCAR protection
The DEFCAR function, as rule, is used together with the distance carrier command protection
(DISCAR†); hence, the user is required to establish the coordination between the DEFCAR
function and the DISCAR function so that both can operate without interference. The
followings exemplify how to establish the coordination using the DEFCAR settings sand
signals.
†Note: For more information of the DISCAR, see chapter
Relay application: Distance
carrier command protection.
(i)
DISCAR and DEFCAR signals being separated
When the DISCAR signal and the DEFCAR signal are used separately, the user should set
0
for the [
TDEFCF
]. Consequently, the DEFCAR function can trip in
TDEFC
after the reception
of the DEFCAR signal. Figure 2.4-11 shows the relationship of sending-signal, receiving-signal,
and tripping in the DEFCAR function.
