ITU-T Recommendations

Supplement 17 to ITU-T K-series Recommendations provides background information that explains how the various lightning and power fault test configurations and electrical values in Recommendation ITU-T K.44 were derived. Examples show how test procedures can be minimized by knowing how the surge and power fault test conditions can vary with time and voltage. How ITU-T Recommendation K.44 relates to its dependent Recommendations is explained.
