3.1.2. Protection Operation Time Constraint

Considering the speed of the relay and the stability of the system, the maximum and minimum operation time of the relay must be limited. For all the I-ITOCRs, the protection operation time is set between 0 and 2 s. The limit of the protection operation time is as shown in Equations (17) and (18):

$$t\_{\rm min} \le t\_{pr \cdot k}^i \le t\_{\rm max} \tag{17}$$

$$t\_{\rm min} \le t\_{bc \cdot k}^{i\bar{j}} \le t\_{\rm max} \tag{18}$$
