Whoop!

Passed the Electrical Power exam with a 73, guess I studied 3% too much! haha :bananadoggywow: :multiplespotting: Nice job threatta, this was my 2nd attempt.

Going for the hat trick...and also staying up way too late studying this stuff, but here's a brief summary on harmonics... http://ecmweb.com/mag/electric_fundamentals_harmonics/ In this case 60-Hz and 60A are useless information. 3rd harmonic phase currents are additive and are the highest in...

In this problem we are asked to solve per-phase and in order to do that we have to convert the Voltage to per-phase. That's where the root 3 comes in... |Vp|=|VL|/√3. In 3-phase systems line-line voltage is always assumed given unless specified otherwise. Once the voltages are in per-phase...

Root 3 is used in Y or Δ connected loads but in this case we are adding up 3 separate single-phase loads so we multiply by 3.
