Subject: суммарное сопротивление короткого замыкания

Если последовательно с парой трансформаторов, суммарное сопротивление короткого замыкания которых равно 4 Ом, включить ТОУ с сопротивлением 10 Ом, ток короткого замыкания от этой пары составит (138/√3кВ):(4+10 Ом)=5,7 кА

If we connect 10 Ohm CLD in series with a pair of transformers having a total short-circuit impedance of 4 Ohm, the short-circuit current of this pair will be (138/√3kV) : (4+10 Ohm)=5.7 kA.

(collins)
impedance
a measure of the opposition to the flow of an alternating current equal to the square root of the sum of the squares of the resistance and the reactance, expressed in ohms

resistance
the opposition to a flow of electric current through a circuit component, medium, or substance. It is the magnitude of the real part of the impedance and is measured in ohms

reactance
the opposition to the flow of alternating current by the capacitance or inductance of an electrical circuit; the imaginary part of the impedance Z, Z = R + iX, where R is the resistance, i = √-1, and X is the reactance. It is expressed in ohms
