Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...

If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...

Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base.  By removing...

Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...

Years ago I was told that you should always try to write the best report you can.  Many years later I still think on this as one of the better pieces of...

In 2011, with the introduction of it’s Panda search ranking algorithms, Google introduced tools for determining the original author of posts.  The intention...

"I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong...

This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
