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

There are a wide variety of electric traction systems around the world, which have been built according to the type of railway, its location and the technology available at the time of installation. Many facilities seen today were built for the first time 100 years ago, some when electric traction barely took off their diapers, so to speak, and this has had a great influence on what is seen today.
In the last 20 years there has been a gigantic acceleration in the development of railway traction. This has worked in parallel with the development ....etc

design of overhead water tank pdf ppt

RCC WATER TANK DESIGN BASIS


Reinforced Concrete Water tank design is based on IS 3370: 2009 (Parts I IV). The design depends on the location of tanks, i.e. overhead, on ground or underground water tanks. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of RCC or even of steel. The overhead tanks are usually elevated from the roof top through column. In the other hand the underground tanks are rested on the foundation.

Voltage Sag or Voltage Dip (IEC term) is defined by the IEE 1159 as the decrease in the RMS voltage level to 10% - 90% (1% - 90% for EN 50160) of nominal, at the power frequency for durations of cycle to one (1) minute. Also, voltage sag is classified as a short duration voltage variation phenomena, which is one of the general categories of power quality problems.

Voltage sag (dip) durations are subdivided into three categories: instantaneous ( cycle to 30 cycles), momentary (30 cycles to 3 seconds), and temporary (3 seconds to 1 minute). ....etc
