Comparison of PSO-Kapur and DE-Kapur methods to determine ice load on aerial lines

Aerial lines are designed according to the calculated a certain ice load amount. If ice load amount on conductor of aerial line is bigger than the calculated ice load amount, aerial line pole bending or conductor breakage can be seen. Joule effect method is proposed to eliminate ice load effect but primarily, the occurred ice load amount on conductor of aerial line must be determined. Ice load amount can be determined with ice thickness of iced conductor. In this study, ice thickness of iced conductor is determined with image segmentation method, but image segmentation is difficult due to high humidity. So, multilevel thresholding method was used to decrease high humidity effect. PSO-Kapur and DE-Kapur Methods were used as multilevel thresholding method. When these results were compared, it was seen that the result of DE-Kapur method was more close to value of real ice thickness according to the result of PSO-Kapur method.
