Fundamental electrical engineering concepts and theory
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
Electromechanical relays have been the traditional backbone of electrical protection systems. While over recent years these have been replaced by microprocessor...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
I was having a conversation the other day about voltage levels. While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
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...
Low voltage (LV) switchrooms are common across all industries and one of the more common spatial requirements which need to be designed into a project...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
