How an arrester responds to power frequency temporary overvoltages (TOV), is seldom discussed in the literature and a phenomenon that is studied even less.  This ArresterFacts is a short synopsis of the topic that should introduce the reader to some of the aspects of TOV with respect to arresters.  An ATP model of the circuit is also downloadable. 

 Modeling Temperature Rise in Arresters Due to Energy Absorption 

There are many occasions, from the application of arresters to design tests of arresters, where prior modeling and prediction of the final temperature of an arrester after an energy absorption event would be useful.  I have been doing these calculation by hand or with excel for years but recently from within ATP Draw using TACS modules, my favorite arrester and transient modeling tool. This ArresterFacts will cover all the calculation methods mentioned above.
