Excerpt from Transmission Line Formulas for Electrical Engineers and Engineering Students

The first method, which is described in Chapter III, is in the form Of a chart which gives the regulation or voltage drop of a line, and which also shows directly the required size of conductor for given conditions.

In Chapter IV are given formulas for distribution lines and transmission lines only a few miles long. These are extended in Chapter V by means of the constant K to apply to transmission lines of any length in ordinary practice.

For purposes of checking different formulas, and for the calculation of extremely long and unusual lines, the fundamental formulas of transmission lines are expressed by rapidly converging series in Chapter VI. While these series require much more arithmetical work than the K formulas, they will give the exact results to any degree of accuracy desired. The method of convergent Series in volves the use of complex numbers, that is, numbers in which j terms appear. They are easier to handle, however, than logarithms, sines and cosines of angles, or hyperbolic functions, and therefore the use of these other mathematical functions has been avoided.

Descrizione libreria

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
