The object of this book is to teach the beginner the basics of three popular power system analysis programs. These programs are designed to simulate and analyze electrical power generation and distribution systems in normal operation and in short-circuit. The programs also have many add-on options like protection selection, arc flash analysis, transmission line sag & tension, raceway calculations, transient motor starting, etc. The programs have Demo (demonstration or trial) versions to allow people to tryout and learn about them. This book provides the engineer and technologist with information needed to use the Demo versions of SKM, ETAP, and EDSA for load flow and short-circuit analysis. The beginner learns how to use them on a small, but realistic, three-phase power system. The information gained is similar to that which students pay for in company-taught "Introduction to ..." courses. However, with this book, the student avoids paying tuition, learns at times of his own convenience, and can compare the different programs. In this book, load flow (power-flow) and short-circuit analyses are done on a small steady-state three-phase power system with manual methods. Then, each program is used to carry out the same analyses. Since in practice, three-phase systems are the most often analyzed, only three-phase systems will be considered in this book. The DC and single-phase capabilities of the programs will not be considered. The person using this book should already have an analytical electrical background. Academically, he should be educated to at least the level of a university two-year electrical engineering technology program.Binding Type: Paperback

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned.
These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
