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:
Screenshot from online calculator. I know this must be correct because the sum of each vector gives approximately the original values.
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.
