Abstract :
Sulfur Hexafluoride (SF6) is a gas that can be used as an isolation medium in electrical equipment, as well as used in Gas Insulated Switchgear (GIS) in electric power transmission systems. SF6 gas quality affects performance as an isolation medium. SF6 gas quality parameters can be seen from the physical condition of the gas, namely Purity, Moisture Content, Dew Point, and Decomposition Product. SF6 gas quality is analyzed with SF6 Analyzer test equipment. Measurements with SF6 Analyzer using CIGRE Standard, IEC 62271 Standard, IEEE C37.122.1, 1993, namely Purity > 97%; Moisture Content < 840 ppmV; Dew Point < -5°C; and Decomposition Product < 2000 ppmV. Based on the measurement results and the average for each GIS Lontar compartment, Busbar have Purity 99,9%; Moisture Content 25,5 ppmV; Dew Point -53,53°C; and there is no SO2 content. Circuit Breaker have Purity 99,9%; Moisture Content 22,83 ppmV; Dew Point -54,11°C; and there is no SO2 content. DS Tanah have Purity 99,99%; Moisture Content 31,5 ppmV; Dew Point -52,1°C; and there is no SO2 content. DS Pengapit dan Tanah have Purity 99,07%; Moisture Content 83,33 ppmV; Dew Point -44,9°C; and there is no SO2 content. DS Bay Line have Purity 99,99%; Moisture Content 87,25 ppmV; Dew Point -44,32°C; and there is no SO2 content. Current Transformer have Purity 99,99%; Moisture Content 234,5 ppmV; Dew Point -34,62°C; and there is no SO2 content. Voltage Transformer have Purity 99,99%; Moisture Content 285 ppmV; Dew Point - 32,7°C; and there is no SO2 content. Lightning Arrester have Purity 99,99%; Moisture Content 36 ppmV; Dew Point -51,3°C; and there is no SO2 content. Termination Sub System have Purity 99,99%; Moisture Content 22,75 ppmV; Dew Point -54,3°C; and there is no SO2 content. Therefore, no reclamation and absorbent replacement is needed.
