Abstract

The behavior and performance of surge protective devices such as optoisolator under the application of multiple voltage impulse are different from the standard single stroke test. Since opto-isolator now days becomes the most common, economical and reliable device for low voltage and telecommunication systems surge protection, a precise method of testing has to be adopted based on natural characteristics of lightning to accurately determine its performance and capability. In this work, laboratory studies will be carried out on opto- isolator subjected to 1/1OOOμs, 1 kV multiple voltage impulses by using the constructed Multiple Impulse Generator, MIGe. The electrical characteristics responses of opto-isolator that will be studied in this work are; forward current If, forward voltage VF and reverse voltage YR parameters. Generally this laboratory work can be divided into three parts; MIGe experimental work, data collection and analyzed the collected data to determine the effect of multiple voltage impulse on the opto-isolator characteristics. From the experimental work, it has been shown that the multiple voltage impulse has significant effects on the forward current IF and forward voltage VF characteristics of the opto-isolator and no significant effect was observed for. the parameter of reverse voltage, V R·
