Abstract
The calculation of the induced longitudinal
vol 0age takes place wider consideration
of the finite length o:f influencing
high-tension line and in:fluenced telecommunication
line. The current distribution
in all conductor-earth circuits is calculated
taking into account the positiondependent
complex mutual impedances. By
variation of the short-circuit location,
the longitudinal voltage of the telecommunication
line is calculated as a function
of the fault location; in the most
unfavourable fault case it is 20 % smaller
tha.~ the longitudinal voltage evaluated
up to now. The calculation is done
by means of a digital computer by complex
matrix relations in which case a normalization
is given. Thus, the economic and
technical-material requirements for protection
measures may be considerably
lowered.
