  • DISCUSSION ON HIGH VOLTAGES AND THEIR SUCCESSFUL INTRODUCTION

    The Sulfur is stripped of all 6 of its outer electrons. The violent reacting Fluorine is subdued and remains quiet and stable. In fact the compound is so stable that it is better than air and is used as the insulating material in many very high voltage applications, including the construction of capacitors used in Hi-Pot testing [5].
