Abstract

High voltage protection for low voltage AC power circuits is very important to minimize the damage of electrical equipment. Unfortunately, review of performance and safety features in commercially-availabic surge suppressors has shown that sometimes they cannot deliver the proper protection to withstand the high voltage surges. This paper will propose a model for higher capability of discharging high current and providing a constant safer voltage for class C protection system in AC power circuits. Metal oxide varistors (MOVs) are used as surge suppressors. Some configurations of MO17s have been tested to show the difference in protection capabilities. Experiments involving a wide range of high voltage surges revealed that the model provides increased in peak current and energy-handling capabilities for a givenapplication.
