Abstract :
The cooling effect of heat sinks placed between the ZnO elements of a surge arrester is evaluated in the context of the IEC Type Test for thermal stability using transient nonlinear finite element analysis with coupled thermal and electric fields to simulate the entire operating duty type test sequence in IEC60099-4.
