IEEE Guide for the Parameter Measurement of AC Transmission Lines

In this guide, the field testing methodology and techniques are presented for measuring electrical parameters of AC transmission lines. The topics will include safety precautions; requirements for measuring instruments; measurement of induced voltage and current; phase verification and insulation resistance measurement; DC resistance measurement; off-line parameter measurement of symmetrical transmission line; off-line parameter measurement of asymmetrical transmission lines; eliminating power frequency interference during off-line measurement; zero-sequence parameter measurement with adjacent lines in operation and on-line parameter measurement of transmission lines.
