PROTECTION FUNCTIONS
3.1
DISTANCE PROTECTION
Operating time versus reach percentage, for faults close to line
angle.
50 Hz, SIR = 5
All quoted operating times include closure of the trip output
contact
Operating time versus reach percentage, for faults close to line
angle.
60 Hz, SIR = 5
All quoted operating times include closure of the trip output
contact
Operating time for resistive faults > 20% inside the
characteristic
Characteristic shape, up to SIR = 30
Zone time delay deviations
3.2
POWER SWING BLOCKING
Accuracy of zones and timers
688
Tripping characteristics
50 Hz, up to SIR = 30 < 30 ms
60 Hz, up to SIR = 30 < 25 ms
Accuracy
+/- 5% for on-angle fault (on the set line angle)
+/- 10% for off-angle fault
Example: For a 70 degree set line angle, injection testing at 40 degrees
would be referred to as "off-angle".
+/- 20 ms or 2%, whichever is greater
