Splet29. okt. 2024 · The switching surge flashover rate (SSFOR) is determined by numerical integration of the Stress-Strength relationship. The stress in this case is the switching … Splet29. jun. 2015 · The switching impulse test applies a switching impulse wave between each high-voltage line terminal and ground. The test series consists of one reduced voltage wave (50%– 70% of specified test level) followed by two full-voltage waves. Either positive or negative polarity waves, or both, may be used.
