Influence of Compaction on the Electrical Design

The electrical parameters are subject to the line configuration. This chapter analyses different tower configurations for AC and DC line and determines the electrical parameters for each configuration. The sensitivity of the phase and pole configurations in relation to the electrical parameters is described. In addition the various standards employed in the world relating to electrical values and limits are described. The objective of this section is to get a measure or quantification of the influence of compaction (i.e. the reduction of horizontal and/or vertical distances) on the line electrical design. The sensitivity to various parameters is evaluated to quantify the influence of the parameter change. Different configurations and geometries can be analysed to fulfil the regulatory requirements or limits related to the electrical parameters. A summary of these limits in several countries around the world is also included for information.
