Three-phase power, faults & protection — core electrical fundamentals.
Wire wye and delta three-phase connections, compare phasors and live meters, and run a break-before-make reconnection demo.
Watch three voltages 120 degrees apart rotate as phasors and sine waves, and switch between wye and delta to see line voltage change.
Set turns ratio, kVA, load and efficiency and watch secondary voltage, both currents, output power and losses update.
Vary transformer kVA and impedance, cable resistance and working distance to see bolted fault current, arc current and PPE category.
Choose copper or aluminum, AWG size, length and load current and check the result against the NEC 3% and 5% recommendations.
Build the kW, kVAR and kVA power triangle and add a correction capacitor to raise power factor.
