Abstract
To ensure the personnel safety during live working on overhead transmission line (OTL), as well as lightning protection
 cables’ (LPC) isolation integrity maintaining, by the example of three-phase 750 kV OTL has been presented an algorithm
 for calculation of voltages, electro-moving forces and currents induced by single phase short-circuit currents’ magnetic field
 of OTL in LPC1 grounded in one point, and in LPC 2 (with fiber-optic communication line function) grounded at every tower.
 For single-phase short circuit modes has been presented an algorithm for length selection of grounded on one end LPC1
 part on the condition of compliance with the maximum permissible voltage level on a spark gap which bypasses an
 insulator set of LPC1.
