The role and application of cast voltage transformers
Casting voltage transformers can convert high voltage into a lower standard secondary voltage according to the proportion, so that the equipment voltage meets the rated voltage requirements, and can effectively isolate the high voltage from electrical workers to ensure worker safety. This equipment is developed and produced based on the principle of electromagnetic induction, but its electromagnetic structure has its own characteristics. So, let's learn about the function and application of casting voltage transformers!

What factors affect the error of a molded current transformer?
The factors affecting the error of shell-type current transformers mainly manifest in two aspects. Knowing the error, how to reduce it? We found that the magnetizing current is the main factor causing the error to increase, so the error can be reduced by reducing the magnetizing current, such as increasing the cross-sectional area of the iron core, shortening the magnetic path length, selecting high-permeability material as the iron core, limiting the secondary load, and appropriately increasing the transformation ratio, etc.

How to prevent open circuit of molded-case current transformer? Regarding this issue, the molded-case current transformer company reminds you that when using this type of product, you need to comply with the electrical safety regulations, and the secondary side must be grounded. The main purpose of this is to prevent the high voltage on the primary side from entering the secondary side, thus causing harm to equipment and personnel.

What factors affect the error of a molded current transformer?
The internal parameters of the molded-case current transformer are the main factors causing errors. The secondary winding's internal resistance R2 and leakage reactance X2 have a significant impact on the error. If R2 increases, both the ratio error and phase angle error will increase. When X2 increases, the ratio error will increase, but the phase angle error will decrease. To reduce the error value, it is necessary to reduce the values of R2 and X2.
