Abstract

Tapping power from the optical power ground wire（OPGW）of a transmission line is an ideal method to power online monitoring device.In this study

the power tapping principle of OPGW grounded to each tower of a typical transmission line is analyzed

and the possibility of power tapping is discussed according to the electromagnetic induction theory of ground wire of overhead transmission line.Consequently

schematic diagrams of the power tapping and the corresponding power-tapping load wiring are drawn.Example of a single-circuit line is taken to calculate power-tapping load’s voltage

current and power using the software EMTP-ATP

and the effects of load impedance

line span

conductor transposition

tower footing resistance on the above parameters are analyzed.Calculation result shows that under appropriate phase current

large power can be obtained for reasonable value of power-tapping load.Finally

a power tapping device is designed and measured on a real transmission line

verifying the work in this study.
