Sažetak
400MVA, 400/220kV Phase Shifting Transformer is in full commercial operation in Zerjavinec Substation since July 2004. Since then, a few external faults happened which has been used to check proper behavior of existing transformer differential protection relays. At the same time the disturbance records from these faults has been used to successfully test a new possibility for differential protection of such transformer. By using these records it has been shown that, with numerical technology, it is feasible to use dynamic, on-line phase angle shift compensation for differential protection of phase shifting transformers.
