What Is a 132kV Transformer?

A 132kV transformer is a high-voltage electrical transformer designed for power transmission systems operating at 132 kilovolt. Its main function is either:

• Step-up transformation
• Step-down transformation

In a power generation station, the transformer may increase voltage from 11kV or 33kV to 132kV for long-distance transmission. In substations, it usually reduces 132kV to lower voltage levels such as:

• 66persegi panjang
• 33persegi panjang
• 11persegi panjang

This process improves transmission efficiency and reduces power losses.

The most common applications include:

• 132kV substation transformer
• 132kV transmission transformer
• 132kV utility transformer
• 132kV transformer for solar plant
• 132kV transformer for wind farm
• 132kV transformer for power plant

How Does a 132kV Power Transformer Work?

The operating principle of a 132kV power transformer is based on electromagnetic induction.

When alternating current flows through the primary winding, it creates a magnetic field inside the transformer core. This magnetic flux induces voltage in the secondary winding.

The voltage transformation ratio depends on the winding turns ratio.

Misalnya:

• Primary voltage: 132persegi panjang
• Secondary voltage: 33persegi panjang

The transformer reduces the voltage for local distribution systems.

Demikian pula, a step-up transformer can increase voltage for transmission purposes.
