Functional diagrams for protection

The functional diagrams describe the protection functionality of the IEDs in detail and
according to the factory set default connections.
Five overcurrent stages are offered for overcurrent and short-circuit protection. Two
of them include directional functionality DPHxPDOC. Three-phase non-directional
overcurrent protection, instantaneous stage, PHIPTOC1 can be blocked by energizing
the binary input X130: BI1.
