Power System Overvoltages and Insulation Coordination – Part 1
Note: This is the first part of power system voltages and insulation coordination.
Insulation coordination is dealt with for three phase AC systems with nominal voltages Un > 1kV in IEC 60071. The insulation of equipment must be designed in such a way as to withstand all foreseeable voltage stresses or to limit the damage in insulation to the faulted...
Neutral Grounding
Introduction
In power system, grounding or earthing means connecting frame of electrical equipment (non-current carrying part) or some electrical part of the system (e.g. neutral point in a star-connected system, one conductor of the secondary of a transformer etc.) to earth. This connection to earth may be through a conductor or some other circuit element depending upon...

Understanding the Concept of Earthing In Electric Power System
Note: This is a paper published in the IOSR Journal of Electrical and Electronics Engineering (IOSR-JEEE), Volume 11, Issue 3 Ver. III (May. – Jun. 2016), pp. 29-33
Earthing is the concept of connecting a thing to the earth (or ground). In Power systems engineering, earthing is the one concept that cannot be dispensed with. Generators, reactors...
Compliance to Statutory Laws
I was reminded of this article which I have written about many years ago when I attended some product presentations about variable speed drives.
What catch my attention most was the closing words of the presenter that he just hate AS 3000 because most of his clients want him to comply with that standard, which is...
