Research on alternative dielectric gases to eliminate the disadvantages of SF 6 , which is widely used in GIS and switching systems in the power system engineering, has been an important study topic in the literature for nearly 40 years. Because of environmental priorities defined by international agreements such as the Kyoto Protocol and Doha Amendment, the restrictions on the use of SF 6 make these studies an obligation. Although the number of alternative dielectric gases studied for this purpose is quite high, these gases can be classified under the titles of non-synthetics, hydrocarbons (HCs), fluorocarbons (FCs), hydrofluorocarbons (HFCs), fluoronitriles (FNs), fluoroketones (FKs) and other synthetic gases. In this study, the gases classified under these titles are compared using the dielectric constant relative to SF 6 , Global Warming Potential (GWP), atmospheric lifetime, boiling point and toxicity parameters used in the comparison of dielectric gases. When compared with these parameters, non-synthetic air, CO 2 , and N 2 , C 3 F 7 CN from FNs, and C 5 F 10 O and C 6 F 12 O from FKs stand out among alternative gases to SF 6. These alternatives are used in some innovative power system industry applications and have a widespread use potential in the insulating gas industry instead of SF 6 .

Classification of abnormal location in medium voltage switchgears using hybrid gravitational search algorithm-artificial intelligence

In power system networks, automatic fault diagnosis techniques of switchgears with high accuracy and less time consuming are important. In this work, classification of abnormal location in switchgears is proposed using hybrid gravitational search algorithm (GSA)-artificial intelligence (AI) techniques. The measurement data were obtained from ultrasound, transient earth voltage, temperature and sound sensors. The AI classifiers used include artificial neural network (ANN) and support vector machine (SVM). The performance of both classifiers was optimized by an optimization technique, GSA. The advantages of GSA classification on AI in classifying the abnormal location in switchgears are easy implementation, fast convergence and low computational cost. For performance comparison, several well-known metaheuristic techniques were also applied on the AI classifiers. From the comparison between ANN and SVM without optimization by GSA, SVM yields 2% higher accuracy than ANN. However, ANN yields slightly higher accuracy than SVM after combining with GSA, which is in the range of 97%-99% compared to 95%-97% for SVM. On the other hand, GSA-SVM converges faster than GSA-ANN. Overall, it was found that combination of both AI classifiers with GSA yields better results than several well-known metaheuristic techniques.

SF6 gas is gas as a filler material for insulating material in Gas Insulated Switchgear. The Kyoto Protocol issued amendments to limit and reduce the use of SF6 gas in various applications, especially as gas isolation applications in substations because SF6 is gas that contributes to the greenhouse effect, the occurrence of global warming and the cause of the ozone layer depletion. This study investigated the use of CF3CHCl2 gas as a new gas to replace SF6 gas as insulation gas. The use of mixture N2/CO2 gas aimed to reduce the main gas concentrate if it leaked into the air and to reduce the cost of procuring the main gas material. The high voltage test showed that CF3CHCl2 gas mixed with N2/CO2 gas was able to withstand a breakdown voltage of 752-837 kV. The ability to withstand the breakdown voltage of the N2 gas mixture is 9 kV-26.7 kV lower than the CO2 gas mixture. The techno-economic value of the use of CF3CHCl2 gas mixed with N2/CO2 gas gives a cost of 5.18 times cheaper than the cost of procurement SF6 gas. The use of CF3CHCl2 gas mixed with N2 gas gives a cost of 1.01 times more expensive than a cost of the use of CF3CHCl2 gas mixed with CO2. In the future, the priority gas is CF3CHCl2 gas as a new gas material that needs to be considered as a potential alternative gas to replace SF6 gas.
