Calculation

Yes. Loads of people can.

This is a very good first step until you get your EE degree in power engineering.

Your question indicates that you're the one that doesn't know that it is not formula-based and requires detailed knowledge of the system and its components.

If I told you to take the reciprocal of X"d and add it to the reciprocal of Xs would you know where to get the data and what to do with it? Indicate a scrap of knowledge from the degree that you bought and you might get some help.

Hire a electrical consultants to do it for you. Your question show that you did even know what is asymmetrical short circuit. There is no information on what you are asking.

1.Asymmetrical Short Circuit Current
Short circuit current normally takes on an asymmetrical Characteristic during the first few cycles of duration [4]. The asymmetrical short circuit current for the High Voltage (HV) and the Low Voltage (LV) windings are calculated
= .................. (1)

Where,

Iph = Rated Phase Current
R = % Resistance
X =% Reactance
Ez = Per unit impedance
R/X = 0.6/6.222 = 0.0965
For HV Winding =
Isc = 894.2 A
For LV Winding =, where π = 3.141
Isc = 82089.5 A

Refer IEC 60909

Hi!

I think that it is quite complicated to show you the details of calculating asymmetrical short circuit currents for a three phase system. However, I can tell you that the calculation is done based on the method of symmetrical components. The fault becomes more complex depending on the scale of the power systems. In the case of a power network containing hundreds of buses, you are even unable to calculate short-circuit by hand. So, you have to use a software to do this. To understand more on short-circuit calculation, you can refer to this link http://www.psa-outline.com/fault-anlysis/

Good luck!
