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

various valves and fittings are required for the safe and proper working of a boiler . Those attached directly to the pressure parts of the boiler are referred to as the boiler mountings.
Minimum requirements for boiler mountings
two safety v/v's
one stm stop
two independent feed check
two water gauge or equivalent
one pressure gauge
one salinometer v/v or cock
one blowdown/scum v/v
one low level fuel shut off device and alarm ....etc

Electricity often travels over very long distances to reach urban load centres. For example, the distance between Baie-James region where water from the Grande Rivi re ends up after driving the turbines in eight power stations and Montr al is about 1,000 kilometres as the crow flies. However, the farther electricity must travel, the greater the risk that part of it will be lost on the way. Since utilities invest heavily in the high-volume transmission of power over long distances, they take special steps to limit these transmission losses.W ....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
