(1)
The minimum value of this trip is 1s regardless of the type of curve set
(self-protection).
(2)
These tolerances apply in the following conditions:
- self-powered relay at full power (without start-up)
- presence of auxiliary power supply
- two-phase or three-phase power supply
- trip time setting
≥100ms
For all cases not covered by the above hypotheses, the following tolerances apply:
Protections Trip threshold Trip time
L Release between 1.05 and 1.25 x I1 ± 20%
S ± 10% ± 20%
I ± 15% ≤ 60ms
G ± 10% ± 20%
Others ± 20%
