The standard aims to consolidate AC and traction voltages within the industry and defines the following bands:
Electromagnetic compatibility (EMC) is the study of coordinating electromagnetic fields give off equipment, with the withstand (compatibility) of other equipment within the vicinity. In it's simplest... read more..
Steel ladders, trays and baskets form the backbone of cable containment systems. Often these items need some form of surface treatment to prevent corrosion due to the installed environmental conditio... read more..
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 (connection of the earthing system t... read more..
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with their most useful properties in relation to electr... read more..
Many medium voltage (MV) indoor switchgear rooms exist worldwide. The complexity of these rooms varies considerably depending on location, function and technology adopted by the owner. This articl... read more..
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. Main LV switchrooms w... read more..
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company or group/department document control systems may... read more..
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances are plugged in to. For larger amounts of power,... 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. It is also possible to use the IEEE 485 method ... read more..
When looking at the design of a lighting scheme it is useful to have an understanding on the nature of light itself and some of the basic theory associated with this. This article provides an over... read more..
Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus. ...
Induction motors are frequently used in both industrial and domestic applications. Within the induction motor, an electrical current in the rotor is induced...
Years ago I was told that you should always try to write the best report you can. Many years later I still think on this as one of the better pieces of...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
When sizing cables, the heat generated by losses within any sheath or armour need to be evaluated. When significant, it becomes a factor to be considered...
Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
