Understanding the New Energy Handling Tests of IEEE C62.11

There are many parameters of arresters, but its energy rating is near the top in importance. Since arresters are installed on power systems to clamp both lightning surges and switching surges, they can dissipate fairly high levels of energy in the course of this activity. However, high voltage arresters are designed to handle this energy. Since there are numerous arrester types and functions, there are several different energy ratings to consider.
