The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...

Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames. Low smokes cables have a sheath designed...

Our question and answer system while letting you do exactly what it says, is much more.  It is a dynamic user driven system, where our users not only ask...

Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss.   The varying electric field causes...

We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.

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)...

Steel ladders, trays and baskets form the backbone of cable containment systems. Often these items need some form of surface treatment to prevent corrosion...

I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...

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...
