Studi Kasus Kegagalan Transformator Berbasis Analisis Dissolved Gas Analysis Dan Breakdown Voltage Pada Pt Kilang Pertamina Internasional Refinery Unit Ii Dumai

ABSTRACT
In electric power distribution operations, transformers are not free from failure.
One of the causes of transformer failure is excessive heat which often occurs in the
transformer isolation system. In this research, two oil testing methods were used,
namely Dissolved Gas Analysis and Breakdown Voltage which were carried out at
PT. Kilang Pertamina Internasional RU II Dumai to know the condition of the oil
insulation being used. In DGA, the analysis method used is TDCG, Key Gas,
Roger’s Ratio, and Duval's Triangle which aims to detect failures in transformer
oil insulation. Meanwhile, for BDV, an analysis is carried out based on the average
test results to see the quality of the oil insulation. From this research, the results of
DGA analysis using four interpretation methods show that the insulation
temperature of the T5-4 transformer oil exceeds 700 ̊C. Based on the IEEE C.57-
104.2008 standard, temperatures above 100°C indicate failure in the form of
overheating. In the BDV test, the breakdown voltage value of the T5-4 transformer
was 24.48 Kv. Based on IEC 60156 standards, good oil insulation should have a
breakdown voltage above 30 kV. So it can be concluded that the quality of the oil
insulation is poor. The validation test results for gas C2H4 and C2H6 over time show
an upward trend. Bagus Tri Setiawan's research shows the same upward trend.
Likewise with the theory expressed by James H. Harlow. Based on the statement
above, the research conducted is valid.
Keywords: Transformers, Dissolved Gas Analysis, Breakdown Voltage.
