is valid for values exceeding the tripping threshold of the protection.
(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)
The tripping threshold of the current for voltage values between Ul and Uh is calculated by performing the linear interpolation between the
thresholds Uh and I20 (first point on the line) and Ul and Ks * I20 (second point on the line). I
threshold
= [I20 * (1 - ks) * (U
measured
- Uh)] / (Uh - Ul) + I20.
(4)
The startup of protection UP is to be considered as the temporary deactivation time of the protection, starting from the exceeding of the startup
threshold.
(5)
ANSI / IEEE C37-2 encoding.
(6)
The setting of the Ks threshold must guarantee the following constraint: Ks * I20 ≥ 0.6 In.
(7)
The setting of thresholds Uh and Ul must guarantee the following constraint: Uh > Ul.
