Mitigation of Magnetic Field under Double-Circuit Overhead Transmission Line

This paper studies the effect of various mitigation loop configurations namely: single horizontal mitigation loop (two conductors), two separate horizontal mitigation loops (four conductors) and single vertical mitigation loop (two conductors), on the magnetic field produced by 220 kV double-circuit overhead transmission line. Also, in this paper a further reduction in the magnetic field is ach...

Design and selection criteria for HVDC overhead transmission lines insulators

Application of GPS for Sag Measurement of Overhead Power Transmission Line

Overhead conductor sag may be measured by different methods. In the paper measurement of sag of 66KV power transmission line under shut down conditions at no wind load using standard handheld GPS receiver BT 359 has done. The real time direct measurement of overhead conductor sag is needed for the operation of power transmission system. The measurement of conductor tension, temperature and ambi...

Evaluation of the Lightning Performance of an Overhead Multiconductor Transmission Line System

The lightning performance of an overhead Multiconductor Transmission Line (MTL) system is typically represented by means of curves reporting how many lightning faults per year the system may experience as a function of its insulation level [1]. In other words, it expresses the probability that the lines are subject to an overvoltage greater than their critical flashover voltage (CFO). Such curv...
