Do you know what the short circuit impedance of transformer is?

Transformer such as the oil immersed transformer, it is an important electrical equipment, in the process of use to enhance the use of the transformer and efficiency of continuous improvement, because the voltage of the transformer is affected by many factors, the voltage control, use and adjust the pressure is not the same.

The impedance of short circuit to transformer is also a main reason that affects transformer work, and it is also one of the most effective means to control voltage.

Then in the actual operation and work, the transformer's short-circuit impedance is what mean, here we give you a detailed introduction:

Concept of A

In general, the short-circuit impedance of a transformer refers to the equivalent series impedance Zk=Rk+jXk between the terminals of a pair of windings at the rated frequency and the reference temperature.

As its value is determined by load test in addition to calculation, it is customarily called short circuit voltage or impedance voltage.

Concept of B

Short-circuit impedance is a very important item in transformer performance index.

Influence of transformer short-circuit impedance on transformer operation:

Transformer short-circuit impedance is also called impedance voltage, in the transformer industry is defined as follows: when the transformer secondary winding short-circuit (steady state), the primary winding flow rated current and applied voltage is called impedance voltage Uz.

Usually Uz in the percentage of rated voltage, that is, Uz =(Uz/U1n)*100%
