STUDI PENUAAN MINYAK TRANSFORMATOR DISTRIBUSI

Abstrak

This study aims to: (1)Determine the effect of transformer oil usage on the dielectric characteristics, physicalproperties and chemical properties of transformer oil, (2)know the effect of transformer loading level on thecharacteristics of dielectric, physical properties and chemical properties of transformer oil, and (3) know the correlationbetween the level of loading and the service life of transformer oil.The results showed that the physical and chemical properties of transformer oil increasingly experienceddeterioration that is the color of the oil became darker, viscosity values experienced an average increase of 0.528Cst peryear, the flash point was lower with an average reduction rate of 4.4827 oC per year, levels the acid gets higher with anaverage increase of 0.00137KOH/gram per year, as well as the electrical properties of transformer oil also experiencedeterioration namely the penetrating voltage decreases an average of 3.885 kV/cm
