Title: Energy Systems and Electrical Networks; Reduction in the magnitude and duration of voltages induced in overhead transmission lines

Abstract

Measures to reduce the magnitude of voltages induced during prolonged operating modes of influencing overhead transmission lines, and also to lower the magnitude and shorten the duration of short-lived induced voltages, which, in a number of cases, will permit use of the traditional sequence of work production on the lines during which several crews can work simultaneously on the line and line equipment at the substations, are discussed; here, no partitioning of the transmission line into electrically uncoupled sections is required.

  • This study analyzes the effects of other conductors in a multiconductor overhead line on the voltages induced on a conductor by a nearby lightning strike, based on the previous studies on long single-conductor overhead lines. The presence of other conductors affects the induced voltage of a conductor, particularly for vertically configured lines; however, the amount is less than that originally predicted. Ground wires reduce the magnitude of the induced voltages, thus acting as partial shields.
  • Equations to calculate the inducing scalar and vector potentials produced by inclined return strokes are shown. Equations are also shown for calculating the induced voltages on overhead lines where horizontal components of inducing vector potential exist. The adequacy of the calculation method is demonstrated by field experiments. Using these equations, induced voltages on overhead lines are calculated for a variety of directions of return strokes.
  • Cleveland Electric Illuminating Co. and Ohio State University present (1) a model of the system involving parallel pipelines and power transmission lines and (2) equations to accurately predict the expected induced voltages on pipelines. Case histories of tests include evaluations of variables influencing induction.
  • A method is developed for calculating the induced voltages on fence wires/pipelines underneath AC power transmission lines. The method is based on the charge simulation technique and takes into account the disturbances of the electric field and potential due to the presence of the fence wire/pipeline underneath the line. The calculated values of the induced voltage on fence wires are compared with those measured before. Induced voltages on pipelines underneath 230- and 380-kV lines are measured, correlated to the calculated values and discussed in the light of electric field induction on objects adjacent to AC power transmission lines.
