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 advice. Not only does this apply ... read more..
Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus. Good engineering design needs to go b... read more..
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
This morning I was explaining how differential protection works to a junior engineer. To give him something to read I opened up the NPAG (Network Protection...
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...
IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The...
From the earliest times, humans have found ways to create light. Pre-historic peoples used natural materials (moss, grass, etc.) soaked in animal fat and...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
Recently I have seen a few interesting articles on viable cold fusion; the combining of atoms at room like temperatures to create boundless energy. Now...
