Calculation of t is valid for values exceeding the tripping threshold of the protection.
t
(2) Valid tolerances with steady-state energized trip unit or trip unit energized by auxiliary power supply, tripping time ≥ 100 ms, temperature and
currents within operating limits. If these conditions are not guaranteed, the tripping time tolerance of ± 10 % will become ± 20%.
(3)
For the startup functions, the specified time is the period during which the protection with the different threshold remains active, calculated from the
moment the startup threshold is exceeded.
(4)
ANSI / IEEE C37-2 encoding.
(5)
Valid tolerance for frequencies in the range: fn ± 2 %. For frequency outside the range a tolerance of ± 5 % applies.
