  • Abstract
    Porcelain insulators subjected to long-term d.c. stress at temperatures in the region of 100°C have been found to suffer a deterioration in their surface vacuum breakdown strength. The letter details some preliminary investigations into this `electrolytic aging¿ effect, and, in particular, the effects of voltage reversal are described.
