Aging of transformer occurs as the transformer operates. Dielectric characteristics testing of oil insulation in transformers is needed to estimate the condition of transformers due to aging. Insulating materials in long-term operations will degrade gradually and cause the change of its properties. In this paper, a database of result for dielectric characteristics was analyzed statistically using...
Dissolved Gases and Oil Characteristics are widely available data for detecting faults and evaluating condition of oil-impregnated power transformers. This paper presents the statistical insights of the effect of transformer paper deterioration to oil insulation. The oil characteristics, dissolved gases, and 2FAL data of 108 Indonesian transformers are collected. 2FAL is used as paper condition parameter...
This Transformer experiences aging everyday as it gets older. The aging of transformer can be detected by assessing the condition of its oil insulation. Every transformer has its own aging rate which is influenced by many factors. This paper discusses about effects of lifetime and loading factor on DGA using regression linear method. 219 sample data including DGA and transformer age were collected...
This paper presents the possibility of using Adaptive Neuro Fuzzy Inference System for Power Transformer Paper Condition Assessment. The dielectric characteristics, dissolved gasses, and furan of 108 running transformers is collected. The 2-furaldehyde (2FAL) data is transformed to Degree of Polymerization (DP), and then statistically analysed to get independent variables as the predictor for the...
