FAQ

1.What are the advantages of power transformers?

The transformation of electrical energy enables the power to be output at a longer distance, enhances the stability of the system, and enables the power to be better distributed to users.

2. What are the modes of supply and distribution of transformers?

Most of the transformer power supply users choose D/yn11 direct grounding neutral system operation mode, which can realize three-phase four-wire system power supply.

3. What are the safety technical requirements of distribution transformer installed in the open air?

The distance between transformer and combustible buildings should not be less than 5m, the distance from fire-resistant buildings should not be less than 3m.


Latest News

In the operation of distribution transformer, there are some cases that the equipment is overheated or even burnt out due to overloading or over current.The improper capacity selection of this device affects the reliability and economy of power supply of the power system.
