I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

A power system functions normally until after the occurrence of a fault in the system. The good news is fault events can be minimized or avoided through diligent electrical design, accurate record ...
