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 from operating transformers in PT. PLN (persero). Specifically, the age of transformer ranges from 0 to 30 years and the rated voltage are 150/20kV and 150/70kV. The result shows that CO, CO2, CO+CO2 and TDCG have strong correlations with transformer age. The strongest correlation is between CO and transformer age with correlation coefficient 0.715. Trend analysis of CO and CO2 are carried out from transformer with various loading factors while the capacity and rated voltage are remained the same. The capacity of transformers discussed is 60MVA with rated voltage 150/20kV and 150/70kV. Loading factors of transformer ranges from 20 to 70%. Trend analysis shows that Transformer with higher loading factor will produce CO and CO2 more than transformer with lower loading factors. Higher loading factor in transformers will also cause CO and CO2 in its oil insulation increase faster.

In Indonesia, there are many capacitor bank installed to regulate the nominal voltage. Currently, the Recovery Voltage (RV) data related to the capacitor bank switching is unavailable, whereas this data is very important to analyze Circuit Breaker (CB) performance to understand whether it will success to interrupt the current or not. In addition, if the CB cannot retain the RV, it will degrade the CB contacts and possible to broke the CB. Therefore, this paper presents the study of RV for 150kV electrical system in Indonesia. The Result showed that the RV is affected by the source impedance value. Furthermore, for normal condition, the value of RV on the CB for capacitor bank with neutral grounded or ungrounded remains within the limits permitted by the standard. However, in the short-circuit condition, the Transient Recovery Voltage (TRV) and Rate of Rise of Recovery Voltage (RRRV) values can exceed the standard values. This TRV problem can be solved by grounding the capacitor bank. Meanwhile, RRRV problems can be handled by installed a surge capacitor that mounted and arranged in parallel (phase to neutral) to the CB.

Occurrence of surge voltages and surge currents in low-power circuits is initiated primarily because of two sources, i.e, natural lightning and switching phenomena; the other source of surge occurrence is possibly due to the interaction of power systems and communication system. Results have indicated that soil resistivity is crucial in determining the adequacy of an earthing system. In region with the highest resistivity, the EPR and the scalar potential of the cabinet are very high. Remarkable low induced voltages at 200 m away from the power line when subjected to a single phase-to-earth fault was observed. At 50 m away, step and touch voltages could be dangerous due to the nature of soil in the vicinity. In addition, a 132 kV double circuit transmission line sharing the same corridor with a telecommunication line was also investigated and have also shown the induced voltages in the order of thousand volts on the cable due to a single phase-to-earth fault. Cables must be protected from such dangerous voltages. During normal peak load conditions voltages are considered not to inflict any damage to equipment and livestock.

Gas insulated switchgear assumes an indispensable equipment for high voltage transmission of electrical energy because of its focal points of high unwavering quality and execution, smaller in measurements and extraordinary compatibility with the environment. It utilizes sulphur hexafluoride gas as its insulant and coolant in view of its high dielectric quality and superb circular segment extinguishing capacity. Gas insulated switchgear in operation suffers the challenge of its insulation deterioration that leads to its failure due to the activities of partial discharge that is caused by defects. This failure is calamitous and it will prompt to whole power out stage that will affect all classes of human exercises. In order to monitor the condition of GIS, in this studies a simulated coaxial decomposition chamber was designed and used to simulate the decomposition of SF6 under the effect of fixed copper (Cu) and aluminium (Al) foil metallic artificial defect on the surface of the spacer in the chamber at the pressure of 0.2MPa when energizing with high voltage for a period of about 50 hours. The decomposition products of Cu and Al foil fixed defects detected offline by FTIR spectrometer are HF, SOF2, SOF4, SO2F2, SO2F10, SiF4, SO2, CO, C2F6, CF4 and SO2, SO2 F2, C3F8 and C2F6 respectively. These decomposed products and its concentration identify the type and the magnitude of fault in switchgear (contamination fault) and it shows that Cu fixed defect is more harmful to GIS than fixed Al foil defect.

Our life is becoming faster day by day by the blessing of the internet of things (IoT). It plays a vital role to reduce the time to complete a computer-based or IT related work. Cloud and fog computing are one of the main elements of IoT which helps to provide service accurately in fewer times. A significant portion of the work related to fog and cloud computing indicates that fog computing is better than cloud computing. In this paper, we focus on time sensitive data like brain stroke, heart attack, accident, etc. and use fog computing to send the result to the user as early as possible. We have developed two algorithms in this paper. First one is for choosing a fog if the user is in the overlapping portion of fogs. The second one is for user's location change and finding the shortest path among many fogs. At simulation part, we have done experiments on brain strokes data as an example of time sensitive data and also demonstrated the comparison between fog and cloud by doing experiments on execution time, energy consumption cost and network usage. The results of simulation experiments depict that regarding time sensitive things fog computing performs better than cloud computing.

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 transformer paper condition assessment. CO and CO2 are well known as one of the product of cellulose degradation, while interfacial tension, acidity, and color from the oil are statistically correlated with furan. ANFIS (Adaptive Neuro-Fuzzy Inference System) and Multiple Regression (MR) model is built based on the previous statistical analysis, and then the result is evaluated and compared, resulting in better accuracy of ANFIS model. Three different evaluation criteria MAE (Mean Absolute Error), MAPE (Mean Absolute Percentage Error), and RMSE (Root Mean Square Error) calculated from ANFIS prediction are lower than those from MR model, with the MAPE of ANFIS model is 15.38%.

Three different evaluation criteria MAE (Mean Absolute Error), MAPE (Mean Absolute Percentage Error), and RMSE (Root Mean Square Error) calculated from ANFIS prediction are lower than those from MR model, with the MAPE of ANFIS model is 15.38%.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"27 1","pages":"237-242"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83341608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
