IEEE TV has a part series of videos on wind power and it's implication. For a really good overview to the technologies and issues around wind power, these videos are excellent. Each video is around 10 m... read more..
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)...
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...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
There are a lot of interesting two page type notes on various medium voltage topics – switchgear, circuit breakers, bus systems etc. It is on the Siemens...
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...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
Electromechanical relays have been the traditional backbone of electrical protection systems. While over recent years these have been replaced by microprocessor...
Photovoltaic (PV) systems are typically more efficient when connected in parallel with a main power gird. During periods when the PV system generates energy...
This morning I was explaining how differential protection works to a junior engineer. To give him something to read I opened up the NPAG (Network Protection...
