A new practical calculating method is proposed according to short current calculation in practical work.

A formula for short current calculation in low voltage power grid distribution was put forward.

This paper presents that the selection of ratio and steady state test depend on the maximal short current,protection setting value and secondary load in .

The breaking of 1000/500kV electromagnetic loop network and the influence of short circuit of UHV is also primary analyzed,based on them the measure and advice is presented.

To obtain the batteries’ short circuit properties, the inner resistance and inductance must be known.

However, if is an out short circuit happens, the decrease of the short circuit of the Shunt Self generator will be slower than Shunt Self generator at the beginning, and during the second half time the decrease will become very fast which, the author suggests, may impair the excitation ability of the generator.
