Short-circuit Apparent Power of the System
In this article, I have presented the effects of utility fault level on low voltage equipment. Assuming an infinite bus as the utility fault level will have a significant cost …
Effect of Utility Fault Level to Low Voltage Equipment Ratings
There are times that the Electrical Engineer are unable to get the utility fault level data to calculate the required electrical parameters for a project. In such case, it is …
Misfits of Design
Even simple projects could be complicated if not properly planned. Inability to respond to site conditions will make conditions even worse as safety will be compromised in all aspects. Some …
Matching the Induction Motor Rating to the Driven Load Power
It is of utmost importance that an induction motor selected for a particular application to have sufficient power and torque to be able to function properly and efficiently. Starting high …
Hardwired vs Software Interlocks
As an Electrical Engineer, I am biased to hardwired interlocks. I don’t have any doubts software can be very efficient particularly during normal operating conditions, not to mention the speed …
Identification of Conductors And Terminals – IEC 60445
The IEC Standard 60445 – Basic and safety principles for man-machine interface, marking and identification – Identification of equipment terminals, conductor terminations and conductors published in August 2010 is a …
