Notes
(1)
The calculation of t
t
is valid for values that have exceeded the activation threshold of the protection.
(2)
Valid tolerances with release energized in service conditions or with the auxiliary, tripping time = 100 ms, temperature and currents within operating
limits. If the conditions are not guaranteed, the tolerance of the tripping time becomes ± 20%.
(3)
The tripping threshold of the current for voltage values between Ul and Uh is calculated by performing the linear interpolation between the th-
resholds Uh and I20 (first point on the line) and Ul and Ks * I20 (second point on the line). I
threshold
= [(I20 * Ks *I20) / (Uh * Ul)] / (U
measured
* Uh) + 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.
