Fundamental electrical engineering concepts and theory
Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...
Working in the vicinity of electrical equipment poses an hazard. In addition to electric shock hazard, fault currents passing through air causes Arc Flash...
Many medium voltage (MV) indoor switchgear rooms exist worldwide. The complexity of these rooms varies considerably depending on location, function and...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
Circuit breakers are switching devices whose primary function is to isolate parts of an electrical distribution system in the even of abnormal conditions...
Some colleagues had an issue earlier in the week on sizing conduits to be cast in concrete for some power cables . It became clear that none of us had...
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...
