Why should we short-circuit the secondary coil of the transformer when testing the leakage inductanc

Why should we short-circuit the secondary coil of the transformer when testing the leakage inductanc

When we use a bridge to test the leakage inductance of the transformer, we need to short-circuit the secondary side, and the inductance obtained by testing the primary side is the leakage inductance. Have you ever thought about why you need to short-circuit the secondary side? What is the principle

Harmonic Analysis of Transformers

Harmonic Analysis of Transformers

The fundamental cause of harmonic generation in power systems is due to nonlinear loads. When the current flows through the load, it does not have a linear relationship with the applied voltage, and a non-sinusoidal current is formed, that is, harmonics are generated in the circuit. Harmonic freque

What is the difference between high frequency transformer and low frequency transformer?

What is the difference between high frequency transformer and low frequency transformer?

The frequency of electricity we use in our daily lives is 50Hz, which we call low-frequency alternating current. If the transformer works at this frequency, we call it a low-frequency transformer, also called a power frequency transformer. This kind of transformer is bulky and has low efficiency. T

Classification of high frequency transformers

Classification of high frequency transformers

High-frequency transformers are relative to audio and industrial frequency transformers. However, because the scale of high-frequency is so wide, it is very difficult to clearly divide them. Therefore, transformers with operating frequencies above audio can be collectively referred to as High frequ
