TELEPROTECTION (NSD600)
Application Transmission of protection commands for line- and objects protection
Number of units 1 or 2 integrated NSD600
Number of commands 4 independent commands for each NSD600, simultaneously transmitted,
individually configurable for blocking, permissive or direct tripping,
plus 1 test command per NSD600
Secure against Noise (continuous or impulsive), speech and sweep tones,
DTMF (CCITT 48430 or ITU-T Q.23) in-band signaling
Bandwidth requirement Nil; command signal transmission in-band (alternate purpose, with signal boosting)
Guard signal ETL-pilot signal, or own guard signal above speech band 2000, 2200 or 2400 Hz
Processing of received signal adaptive (to prevailing channel condition, always ensuring shortest transmission times)
Number and type of inputs 4 optocoupler per Teleprotection Interface G4AI
Method of tripping Contact and battery, or dry contact
Voltage ranges 24 to 250 VDC, selectable in 4 ranges
Number and type of outputs 4 solid state relays and 2 mechanical relay contacts per Teleprotection Interface G4AI
Tripping voltage 5 to 250 VDC nominal
Tripping current ≤ 1 A carry / 2 A peak solid state
5 A carry / 20 A peak mechanical relay
HMI configurable Command and alarm assignments to I/O ports
Command pick-up times, hold times, duration monitoring
State of command outputs during link alarm
Alarm and unblocking levels thresholds
Event logging 2’600 time-stamped events, command counters; stored in non-volatile memory
Teleprotection performance
Performance criteria, description of measurement
Abbrev. Blocking Permissive tripping Direct tripping
Nominal transmission time (back-to-back operation,
including PLC equipment delay and operating times of
the teleprotection interface I/Os; noise free channel)
