Fundamental electrical engineering concepts and theory
Two driverless and solar power vans have departed from Italy on their way to China via the silk road. During the 13,000 kM trip the vans will drive themselves...
Current transformers (CTs) are used to convert high level currents to a smaller more reasonable level for use as inputs to protection relays and metering...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...
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...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
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...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
