Table 69. Rate-of-change frequency protection SAPFRC
Function Range or value Accuracy
Operate value, start function (-10.00-10.00) Hz/s ±10.0 mHz/s
Operate value, restore enable frequency (45.00-65.00) Hz ±2.0 mHz
Definite restore time delay (0.000-60.000) s ±0.2% or ±100 ms whichever is
greater
Definite time delay for frequency gradient trip (0.200-60.000) s ±0.2% or ±120 ms whichever is
greater
Definite reset time delay (0.000-60.000) s ±0.2% or ±250 ms whichever is
greater
