Advantages of dry-type transformers compared with oil-immersed transformers
Dry-type transformer refers to a power transformer whose core and winding are not immersed in insulating oil and adopts natural cooling or air cooling. As a late-emerging power distribution equipment, it has been widely used in power transmission and transformation systems in factory workshops, h...Read more -
Power Transformer: An introduction, Working and Essential Accessories
Introduction Transformer is a static device which transforms AC electrical power from one voltage to another voltage keeping the frequency same by electromagnetic induction principle. Input to a transformer and output from a transformer both are alternating quantities (...Read more -
EARTHING TRANSFORMERS
An earthing transformer, also known as a grounding transformer, is a type of transformer that is used to create a protective earth connection for electrical systems. It consists of an electrical winding that is connected to the earth and is designed to create a neutral point that is grounded. Ear...Read more -
Insulation level of transformer
As an important electrical equipment in the power system, the insulation level of the transformer is directly related to the safe and stable operation of the power system. The insulation level is the ability of the transformer to withstand various overvoltages and long-term maximum working voltag...Read more -
Innovation of Copper Applications in Transformers
Transformer coils are wound from copper conductors, mainly in the form of round wire and rectangular strip. The efficiency of a transformer is crucially dependent on copper purity and the way in which the coils are assembled and packed into it. Coils should be arranged t...Read more -
How do you determine the layout of substation bushings
There are factors: Bushing Locations Phasing Bushing Locations The American National Standards Institute (ANSI) provides a universal designation for labeling transformer sides: ANSI Side 1 is the “front” of the transformer—the side of the unit that hosts the ...Read more -
