Oil Chromatographic Analysis of First HVDC Converter Transformers Project in Pakistan – A real Project Case Study

Abstract

This paper presents the concept of the creation of gasses inside the transformer oil and the fault produced inside the transformer is examined. Focusing on the issue of numerous trademark gases surpassing the norm in a 500 kV transformer oil, this paper dissects the issues keeping in view the trademark gas strategy and three-ratio technique and joined with prior tests, it was decided that the single-phase converter transformer Pole 1-YDA. The on-location review proves the rightness of the disappointment investigation results and the corresponding measures were taken on to dispense with the transformer flaws. Key Words: Converter Transformers, DGA, HVDC, Internal Faults.
