In the case of phase overcurrent protection, the protection is activated when the current value
exceeds the set current value. If the current threshold is exceeded in any of the three phases,
the protection will be activated.
Phase overcurrent protections are indicated by I>, I>> and I>>> in IEC 60617; PHI_PIOC_1,
PHI_PIOC_2, PHI_PIOC_3 in IEC 61850; 50/51P-I-1, 50/51P-I-2, 50/51P-I-3 in
