Performance criteria, description of measurement
Nominal transmission time (back-to-back operation,
including PLC equipment delay and operating times of
the teleprotection interface I/Os; noise free channel)
Security - probability of an unwanted command
(200 ms noise, 200 ms pause, worst case SNR)
Dependability - probability of missing a command
required channel condition
for actual transmission time
1)
Valid for the solid state command outputs, add 5...8 ms for the relay contact command outputs.
