Since some years, arresters with polymer-housings have been available on the market for distribution and medium voltage systems. In recent years, this type of arresters have been introduced also on higher voltage systems up to and including 550 kV. However, the international standardisation work is far behind this rapid development and many of existing designs with polymer-housings for high voltage systems have only been tested according to existing IEC standard, IEC 99-4 of 1991, which in general only covers arresters with porcelain housings. Paper presented at GCC Cigré 9th symposium, Abu Dhabi, October 28-29, 1998.
