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

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...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...

Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...

Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
