Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Earthing of electrical systems is essential for the correct functioning and the protecting of life and equipment in the event of faults. The earth electrode...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
The standard aims to consolidate AC and traction voltages within the industry and defines the following bands: band 1 - A.C. systems 100 V to 1...
It starts with me reading one of the Horrible History books with my son (Groovy Greeks). Arrows were mentioned which lead to the discussion of the bodkin...
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...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
