Abstract :
Insulation design of polymer housed surge arresters for distribution lines are evaluated by using IEC 1109 based salt fog test. The concept of “rest time” in salt fog tests of housings has been introduced with an effort to give fairness to silicone materials. The method provides a comprehensive evaluation of insulation design of polymer housed surge arresters. However, at this time, the inclusion of a rest time in salt-fog tests of silicone rubber housings is not warranted, as hydrophobicity did not recover completely even after a seven-day rest period
