If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light. I’m intending...
IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
Resistors are electronic components that oppose the flow of current. Manufactured in various types and ranges they have a wide application to electronics...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
A frequent problem in fault calculations is the obtaining of equipment parameters. While it is always preferable to use the actual parameters of the equipment...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
Delum, who had watched all in silence, his face empty of expression, now spoke in turn. ' "Lead us, Warleader, into glory."' Reading is something I do...
