Fundamental electrical engineering concepts and theory
Power cables can basically be classified into earthed and unearthed cables, where earthed and unearthed refer to the application for which the cable is...
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...
At the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is...
The windings of many medium and small sized transformers are protected by restricted earth fault (REF) systems. The illustration shows the principal of...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
The widely used United Sates standard ANSI/IEEE C37.2 'Electrical Power System Device Function Numbers, Acronyms, and Contact Designations' deals with...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
