The electromagnetic voltage transformer is the voltage of the primary side, so it will not be affected by the load of the secondary side of the voltage transformer. In most cases, the load of the secondary side is constant.

What are the main types of electromagnetic voltage transformers?

I. Cascade type electromagnetic voltage transformer mainly connects several different transformers in series directly, so that the insulation and heat dissipation problems in electromagnetic voltage transformer can be effectively alleviated.

II. It is equipped with an open iron core electromagnetic voltage transformer. The difference between this type of voltage transformer and traditional transformers is that its iron core is open but not closed, and the voltage can be as high as 550kV. And the error in the open voltage transformer will not be affected by any external factors, and can completely reach level 0.2.

III. With the close type electromagnetic voltage transformer core, in this kind of voltage transformer, normal next winding core and secondary windings are in the same column, while the core is direct contact with the ground, the transformer is placed in the box body of the earth, because of the winding layer number is very much, layer and layer between the need to use the oil impregnated paper insulation, So that we can make a no insulation between the winding layer of oil gap, the advantages of this form of voltage transformer is, for larger impact force and high frequency over voltage, has high capacity, and faults because of the winding layer number is more, so the cooling effect is bad, but if in a winding layer between add oil clearance and electric screen. Then the winding heat dissipation problem can be solved.

We manufacture various precision current transformers and voltage transformers, which are widely used in electric power, energy, telecommunication, railway, industrial control and other fields.
