I've recently come across this question a couple times browsing the internet. Decided to give a quick answer here. A rectifier transformer is a transformer which includes diodes or thyristors in the sam... read more..
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 side. While this is easy for some people to... read more..
Various techniques exist to enable the correct selection of batteries for UPS applications. The procedure described below is one of the more common. ...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
Using software in our work is essential for most of us and we are becoming even more dependant on it's use. While software is a great asset, many times...
IEC 60947 is the circuit breaker standard and covers the marking of breakers in detail. Any manufacturer following this standard should comply with the...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
If you are wondering what happened to our cable notes, the short answer is that we have moved them to myCableEngineering.com. The "Knowledge Base" at...
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...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
