Required arrester condition during leakage current measurement
Transient leakage currents can affect the measurements made. To ensure both
stable readings and the best possible consistency for comparison between measu-
red values, leakage current measurements should not be made while it is raining or
otherwise when large external leakage currents can be expected to flow on the hou-
sing. This is less of an issue for arresters with silicone housings, since such external
leakage currents are lower.
