One of the most productive new approaches to power quality is immunity testing — making sure that loads can tolerate common disturbances without additional filtering or support. This kind of testing ...

The quality of electricity generated varies between generators. Clean power is electricity that maintains a consistent voltage while producing a steady 60-Hz frequency with no harmonics. To achieve ...

Feb 1, 2008 12:00 PM, By Larry A. Bey, Cummins Onan Corp. You've lost normal power. Your engine-generator set (gen-set) starts up and reaches speed. Now, you want to start some large motors key to ...

The hobby circuit below uses an unusual method to generate about 12,000 volts with about 5uA of current. Two SCRs form two pulse generator circuits. The two SCRs discharge a 0.047uF a 400v capacitor ...

These editor-tested models are ideal for camping, tailgating, or powering tools when you’re too far from an outlet.
