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...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...
In the previous note we looked at the approach taken by the standard to the sizing of cables and illustrated this with an example. We then looked at one...
If your are ever called out to troubleshoot something on your electrical system, one of the first things consider is the supply voltage. You want to ensure...
IEC 60287 "Calculation of the continuous current rating of cables (100% load factor)" is the International Standard which defines the procedures and equations...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
Electric motors are one of the most widely used items of electrical equipment. Improving motor efficiency benefits include, reduced power demand, lower...
