Some oil-immersed transformers can be fitted with tap changers, but not all models support this feature.
What is a Tap Changer?
An oil-immersed transformer tap changer is a device that allows you to change the number of turns in the transformer coil. By adjusting the insertion position of the tap changer plug, you can change the transformer's output voltage. Without changing the transformer's capacity or size, a tap changer can increase the transformer's output voltage range.
Do Oil-Immersed Transformers Have Tap Changers?
Not all oil-immersed transformers support tap changers. Some models can be fitted with tap changers, but not all models support them. Therefore, when purchasing an oil-immersed transformer, you need to check whether it supports tap changer functionality.
Precautions for Using Tap Changers
1. Minimize the number of times the tap changer is plugged in and out to avoid unnecessary damage to the transformer.
2. Ensure the tap changer is plugged in correctly; do not plug it in incorrectly or leave it in the wrong position.
3. When installing the tap changer, pay attention to its compatibility with the transformer to avoid affecting the transformer's lifespan.
4. Ensure the tap changer is wired correctly to avoid wiring problems.
