Abstract
Power transformers installed in the 1960s and 1970s were protected by surge arresters with gaps and silicon carbide valve elements. Many of these arresters are still in service but the population is declining. By 1980, gapless zinc oxide arresters were being installed in all new installations. There are two reliability issues involving surge arresters: adequacy of protection and consequential damage resulting from in-service failure.
