Wye Unbalanced RLC Calculation Example

This video is a step by step tutorial on the problem below

Calculate the neutral current on an unbalanced wye connected load using the following values:
Source: 120/208 V, 60 Hz, 3-Phase 4-Wire
Phase A: Coil with 8Ω of Resistance and a power factor of 0.8 Lag
Phase B: 20Ω Resistor
Phase C: Capacitor with a capacitive reactance of 12Ω

0:00 Intro
1:46 Phase A Current
4:28 Phase B Current
5:35 Phase C Current
7:24 Neutral Current

Excellent easy to follow steps. Thankyou Zack

You're the only person i could find who went through the explanation with a phasor diagram and even mentioning a horizontal/vertical chart. Thank you so much Zack! I've been struggling to understand this but your videos have been helping me a lot! I'll be a returning a returning viewer for the next couple months😁

why did you put the voltage phase B at 240 degree and phase C at 120? Should not be phase B at 120 degree and phase C at 240 degree (counterclockwise direction A, B, C) ? And if I have a three-phase circuit with different currents in each phase (unbalance load RLC), I check the phase sequence (with phase sequence device) and it indicates that the rotation is in the left direction this mean that on the phase diagram the direction will be clockwise (from 0 degree I will start to count in clockwise direction opposite compare with your example)?

Thanks for the exercise, how can i calculate the voltage unbalance from a floating neutral 3 phase unbalanced load?¿ thanks!
