GENERAL INFORMATION

What is Idle Loss Test and Why Is It Important?

With the no-load test, magnetic losses in the core of transformers can be calculated during the design phase. Thus, the efficiency coefficient of the transformer can be defined. These losses occur as long as the transformer is operating. Therefore, the idle loss is very important for the business economy. Idle losses in transformers are also called core losses or iron losses. It is an important parameter for the transformer and is a data used in the heating test.

What is Loss-at-Load Test and Why is it Important?

The head loss or copper loss in the primary and secondary windings of transformers is the result of coil resistance. It determines whether the transformer’s windings will be damaged when the transformer is exposed to load.

How to Prevent Transformer Losses?

Power loss is inevitable in a transformer. Even a transformer that is energized but not connected to the load consumes some energy in the form of no-load losses. Transformer losses can be reduced by careful design and proper sizing of its components.
