Transformers have the highest efficiency, do you understand?

Transformer is a common power equipment in power system, and its operating efficiency directly affects the stability and economy of power system. So, where is the highest operating efficiency of the transformer?

Variable loss equals constant loss.

When the variable loss (coil copper loss) of transformer is equal to the constant loss (core loss), the operating efficiency of transformer reaches the highest point. At this time, the load factor β is about 0.6, which is equivalent to 60% of the rated load.

Importance of load factor β

Load factor β refers to the ratio of actual load to rated load, which is an important index to measure the operating efficiency of transformer. When the load factor β is 0.6, the operation efficiency of the transformer is the highest.

Methods to improve the operation efficiency of transformer

In order to improve the operation efficiency of transformer, the following measures can be taken: reducing the no-load loss of transformer, improving the load rate of transformer, optimizing the operation mode of transformer, etc.
