4.5 Breaker Intertrip and Remote Tripping- Direct Local Trip
Breaker Intertrip and Remote Tripping
External Direct Local Tripping
Remote Tripping
Intertripping of all opposite ends when single-end tripping Can be switched on/off
Operating time, total Approx. 6 ms
Trip Time Trip Time DELAY 0,00 s to 30,00 s
or ∞ (ineffective)
Steps 0,01 s
Expiry tolerance 1 % of setting value or 10 ms
The set times are pure delay times
The tripping times refer to the output of commands via high-speed output relays (7SD5***-*N/P/Q/R/S/T)
Tripping of remote ends by a command that is coupled into a binary input
The tripping times depend on the number of ends and the communication speed. The following data presuppose a trans-
mission rate of 512 kBit/s and the output of commands via high-speed output relays (7SD5****-*N/P/Q/R/S/T)
Operating time, total approx.
for 2 ends minimum 7 ms
typical 12 ms
for 3 ends minimum 9 ms
typical 13 ms
for 6ends minimum 13 ms
typical 18 ms
Dropout times, total approx.
for 2 ends typical 19 ms
for 3 ends typical 20 ms
for 6 ends typical 26 ms
Tripping delay T-ITRIP BI 0,00 s to 30,00 s steps 0,01 s
Trip time prolongation T-ITRIP PROL BI 0,00 s to 30,00 s steps 0,01 s
Expiry tolerance 1 % of setting value or 10 ms
The set times are pure delay times
