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, allowing you to shorten the time used for endless calculations of cables, voltage drop, various sections of circuit breakers, capacitors, cable size and so on.

Most of spreadsheets are developed by two electrical engineers and programmers mr. Jignesh Parmar and mr. Hemant Kashikar. They all really did an awsome job, you must admit.

Just to mention that all calculation spreadsheets are free for download!
