Capacitors are widely used in electrical engineering for functions such as energy storage, power factor correction, voltage compensation and many others...

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...

For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...

Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...

Ever wondered what kind of power an aircraft uses when parked at the airport stand. Normally the aircraft generates it own power, but when parked with...

Anyone specifying or using electric motors should have a basic understanding how the insulation is related to temperature. Three classes of insulation...

Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...

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...
