Do You Know What Is The Short Circuit Impedance of The Transformer?

process of using, it is necessary to enhance the continuous improvement of the use and efficiency of the transformer such asDry Type Transformer. Since the voltage of the transformer such asCast Resin Transformeris affected by many factors, the voltage is controlled and used. The pressure of adjustment is not the same. The impedance of the short circuit of the transformer is also a major cause of the transformer's operation and one of the most effective means of controlling the voltage. So what is the meaning of the short-circuit impedance of the transformer in actual operation and operation? Here we will give you a detailed introduction:

Concept A

Generally, 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 a rated frequency and a reference temperature. Since its value is determined by the load test in addition to the calculation, it is customarily referred to as the short-circuit voltage or the impedance voltage.

Concept B

The short-circuit impedance is an important item in the performance index of the transformer, and the deviation between the measured value and the specified value at the time of shipment is very strict.

Influence of transformer short-circuit impedance on transformer operation

Transformer short-circuit impedance, also called impedance voltage, is defined in the transformer industry: when the secondary winding of the transformer is short-circuited (steady-state), the voltage applied by the primary winding to the rated current is called the impedance voltage Uz. Usually Uz is expressed as a percentage of the rated voltage, ie uz=(Uz/U1n)*100%

When the transformer is fully loaded, the level of the short-circuit impedance has a certain influence on the output voltage of the secondary side. The short-circuit impedance is small, the voltage drop is small, the short-circuit impedance is large, and the voltage drop is large. When the transformer load is short-circuited, the short-circuit impedance is small, the short-circuit current is large, and the electric power that the transformer is subjected to is large. The short-circuit impedance is large, the short-circuit current is small, and the electric force that the transformer is subjected to is small.

The above is the impedance effect of the short circuit of the transformer and the basic analysis of the concept for your reference. Everyone can continuously promote the stability and stability of the transformer. In this case, many effects of the transformer will be exerted, and it is safer.
