Fundamental electrical engineering concepts and theory
Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) medium voltage switchgear. Recently we had to change a GIS design to AI...
If two dissimilar metals are touching and an external conducting path exists, corrosion of one the metals can take place. Moisture or other materials...
The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
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...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
These lifts were first built in 1884 by J. E. Hall and called a paternoster ("Our Father", the first two words of the Lord's Prayer in Latin) due to its...
Induction motors are frequently used in both industrial and domestic applications. Within the induction motor, an electrical current in the rotor is induced...
I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
