Application scenarios and applicable environments
This transformer is suitable for industrial and mining enterprises, agriculture and civil buildings, especially for places with oil and chemical substances in the petroleum and chemical industries. Its low-voltage winding with a capacity of 630~2000kVA adopts a cylindrical or spiral structure, with high mechanical strength, balanced ampere-turn distribution, and strong short-circuit resistance of the product.
What is the voltage change rate of the transformer?
The voltage change rate is one of the important indicators to measure the performance of the transformer. When the transformer supplies power to the load, the voltage at the load end will drop. The voltage change rate indicates the percentage of this drop value to the rated voltage value. Through the formula calculation, we can understand the voltage fluctuation of the transformer in actual work, so as to take corresponding measures to optimize and adjust it.
