In the main menu bar select “Calculate” and press the dropdown icon
From the drop-down list choose whether EA-PSM should “Calculate Minimum Short Circuit”, “Calculate Maximum Short Circuit” or “Calculate Both”.
Then calculate “Short circuit K3”, “Short circuit K2”, “Short circuit K1” or “Short circuit K1,1”.
The results will be saved in the short circuit summary table ( Figure 8.3 ) and on the one-line diagram. In the summary table on the left side select the short circuit location, on the upper tab choose short circuit type (K3, K2 ,K1 ,K1 ,1 , min or max). The selected results will appear in the table. Phase voltage and current values are marked UA, UB, UC, IA, IB, IC. Voltage and current values of different sequences are marked ad U1, U2,U0, I1, I2, I0.
Selecting maximum or minimum short circuit icon will allow analyzing the results according to the short circuit location, by choosing the short-circuited bus on the one-line network diagram.
K3
three–phase short circuit
K2
phase – to – phase short circuit
K1
phase-to-earth short circuit
K1,1
two-phase-to-earth short circuit
With EA-PSM user can also calculate peak values of the short circuit current. On the upper left side of the short circuit summary table push button “Peak”. An example of “Peak” values table is shown in the "Short circuit results" table below .Meanings of the short circuit results values are:
Ip
Peak current
Idc0
DC component of the short circuit current at the beginning of the short circuit
Idc100
DC component of the short circuit current after 100 seconds from the beginning of the short circuit,
Ib
Breaking current (estimated current that breaker will disconnect)
R, X
Network resistance and reactance values
It is not necessary to calculate short circuit at all buses of the network. The user can choose at which bus short circuit should be calculated. From “Calculate” drop-down select “Calculate on click”, choose the short circuit types you wish to calculate. Select maximum or minimum short circuit icon (13 in Figure 2.1 ) and now it is possible to calculate short circuits at only one bus, by simply clicking on that bus. Another way of doing this is to specify substation for the bus (4.4. Defining parameters of the regular Busbar) and calculate short circuit at the substation “Calculate” -> “Short circuit” -> “All in substations”.
When in calculated scheme there is a transformer with tap changer, the position of tap changer ir taken into account when calculating. The calculated result depends on the position of tap changer and the changed voltage.
It is not possible to perform the calculations if parts with different voltage levels are shortened. For example, to this scheme:
In this case, there are two parallel lines with the same line length and the same transformers, except the tap changer position of the first transfomer is different than the position of other. In this case, it is not possible to calculate the short circuit current.

short circuit icon will allow analyzing the results according to the short circuit location, by choosing the short-circuited bus on the one-line network diagram.
