Electrical tools (MS Excel Spreadsheets)

This section is dedicated to tools every electrical engineer can use in daily work. These spreadsheets below will make your job much more easier, alowing you to shorten the time used for endless calculations of cables, voltage drop, various selections of circuit breakers, capacitors, cable size and so on.

Spreadsheets are mostly developed by expirienced electrical engineers and programmers (thank you mr. Jignesh Parmar!) and by well known manufacturers of electrical equipment. They all reall ....etc

sag and tension in transmission line ppt

ETAP Transmission & Distribution Line Sag and Tension Analysis module is an important tool to perform sag and tension calculation for transmission and distribution lines to ensure adequate operating condition for the lines. If the tension applied on a line is beyond its limit, the line conductor could be damaged, and the transmission capacity and life span of the line will be reduced. If the sag is too large, it may cause a short circuit between the line and objects below it or a short circuit between l ....etc

Power Upgrading of Transmission Line
by Combining AC DC Transmission



H. Rahman and B. H. Khan, Senior Member, IEE


abstract

Abstract
Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits in order to keep sufficient margin against transient instability. With the scheme proposed in this paper, it is possible to load these lines very close to their thermal limits. The conductors are allowed to carry usual ac along with dc superimposed on it. The added dc power flow doe ....etc
