6. Surge arrester monitoring theory
• Multipliers for the total resistive leakage current and the resistive
third harmonic as functions of voltage stress and ambient tempera-
ture. These multipliers are used for converting the actual values of
voltage stress and ambient temperature at the time of measurement
to standard operating conditions. Examples of such multipliers are
given in Figures 6.3.7 and 6.3.8.
