IEEE 1870-2019 pdf free.IEEE Guide for the Parameter Measurement of AC Transmission Lines.
1.4 Application of distributed parameter measurement of ac lines
Normally in power system calculation, the equiaIent [I representation is used rather than the distributed parameters of the lines.AcILlally. some measurement results described in this guidance are shown as distributed paramctcm. In Annex F. the equivalent fl representation and lunipcd parameter calculation from distributed parameters are indexed and introduced.
