The effect of multiple lightning impulse on the electrical characteristic of opto-isolator as lightning protective devices

The behavior and performance of surge protective devices such as optoisolator under the application of multiple lightning voltage impulse are different from the single lightning voltage impulse test. Since opto-isolator is becoming the most common, economical and reliable device for low voltage syst...
