Why are using breather in current transformer, what is it, and colour

Question

Accepted Answer

Breathers are used in current transformers to prevent moisture and dust from entering the transformer.

Breathers are devices that allow air to enter and exit the transformer, while preventing the entry of moisture and dust.
They are typically filled with a desiccant material, such as silica gel, which absorbs moisture from the air.
The desiccant material changes color when it becomes saturated, indicating that it needs to be replaced.
The color of the breather can vary depending on the manufacturer, but it is commonly blue or pink.
By using breathers, the insulation system of the current transformer is protected from moisture, which can cause insulation breakdown and affect the accuracy of the transformer's measurements.
