[SOLVED] Attempt to calculate symetrical components - get wrong results

[Prototyp_V1.0]

Hi.

I have this calculation issue that I'm not able to figure out what I'm doing wrong (I have used an online calculator so I know my result differs from the true answer).

This is the list of every wrong calculation:

• Positive sequence:
  • Real answer is
    
    
    354∠97∘354∠97∘​
    
    
  • My calculation
    
    
    475∠52,8∘475∠52,8∘​
• Negative sequence:
  • Real answer is
    
    
    333,5∠31∘333,5∠31∘​
    
    
  • My calculation
    
    
    65,6∠127∘65,6∠127∘​
• Zero sequence:
  • Real answer is
    
    
    0,3∠−122∘0,3∠−122∘​
    
    
  • My calculation
    
    
    0,18∠215∘0,18∠215∘​

I cannot tell if the zero sequence is wrong too, because on the web calculator I had trouble to insert decimals and rounded to nearest integer. This small value may be caused on rounding errors. Frankly I don't know if this calculation is also wrong.

Attached files:

1. Screenshot from online calculator. I know this must be correct because the sum of each vector gives approximately the original values.
2. Screenshot from Geogebra. Now after posting I see the naming scheme could be better, but the names relates this way to the names they should have used:

Isymetrisk1 --> positive sequence phase A
Isymetrisk2 --> negative sequence phase A
Isymetrisk3 --> zero sequence phase A


Appreciate any answer that can help pointing out the errors in the calculations.

Update : I was able to calculate the correct results by hand (simple calculator). So I assume the error must lie in how I make Geogebra calculate the results.
