2.2.6. FAULT LOCATION
Before the execution of the fault localization algorithm the prefault, fault and phase
currents are determined. The Takagi algorithm for fault location is currently in use but
the Novosel´s positive sequence, negative sequence and total fault algorithms are in the
process of being incorporated to the relay.
Using the proART software the line data are introduced:
Line length.
Positive sequence impedance.
Zero sequence impedance.
