摘要

The principle scheme and parameters of overhead transmission line distance protection capable of detecting a rupture of a self-supporting insulated wire over 1000 V hanging on railroad AC towers are presented. The protection is based upon phase-to-ground voltage measurement at a line end made in a resistor-capacitor zero-sequence compensation cubicle. A communication carried out over the overhead transmission line.
