I just need the answers in detailes for these qustions

Its for my own referance , I dont really care about any formating its not for submittion in any kind

I just need the answers in detailes to know if my way answering it correct or not

What can you tell about these waveforms: MM IW M w For this current spectrum, calculate: true rms current, % THD-i 700 640 600 500 400 300 200 165 100 75 38 27 18 0 1 2 3 4 un 6 Calculate total power factor if PF(displacement) = 0.85 and PF (distortion) = 0.92 What total harmonic current distortion (%THD-i) would you expect for a six-pulse rectifier with an effective source impedance of 0.5%, 3% 5%? What is the Distortion Power Factor associate if current distortion is 34% THD-i? What is the effective input impedance for a transformer rated 5MVA transformer, 5.75% if the non-linear load is 2000KVA?

Question1
What can you tell from this wave forms:
These waveforms are fundamental waveform with harmonics and of which the harmonic
distortions THD is present.

Question 2
For this current spectrum, calculate:
True rms current
True RMS current = √𝐼12 + 𝐼22 + 𝐼32 + 𝐼42 + 𝐼52 + 𝐼62
√6402 + 1652 + 752 + 382 + 272 + 182
True RM...
