Teach you to confirm these two kinds of transformers
Sep 17 , 2020
In order to accurately measure the power consumption in high-voltage and high-current AC circuits, voltage transformers and current transformers are generally used to convert high voltage into low voltage and large current into small current, and configure a moderate meter to use voltage Transformers to carry out accurate measurements. For example, the current, working voltage, output power, frequ...

What is the difference between a current transformer and a voltage transformer?
Sep 17 , 2020
1. The structure is different: The primary winding of the current transformer is wound with thick lines, usually only one or a few turns, and is connected in series with the load of the measured current; the voltage transformer is a step-down transformer, and its primary winding coil has many turns, which is consistent with the measured current load. The high-voltage power grid is connected in par...

What is the difference in working principle between current transformer and voltage transformer
Sep 17 , 2020
Working principle of current transformer The working principle of the current transformer is similar to that of the transformer. The most critical difference with the voltage transformer is that under normal operation, the pressure drop on the primary and secondary windings is not large, which is equivalent to a transformer with a short-circuit fault condition. Therefore, the magnetic flux Ф in th...

The future development direction of electronic transformers
Oct 28 , 2020
According to media reports, the future research and development directions of electronic transformers include passive sensing, structural combination, functional reuse, and component standardization. Passive sensing: Due to the technical advantages of passive sensing, independent ECT sensing components will tend to be passive. This includes that active sensors will be self-powered and move towards...

A brief introduction to zero sequence transformer
Oct 28 , 2020
Zero-sequence current transformers are also called residual current transformers, ground current transformers or leakage current transformers. They are usually used in power fire protection equipment. When the power system generates zero-sequence grounding current, it is used in conjunction with the relay protection device for pre-protection Or monitor. The basic principle of the zero sequence cur...

Smart grid: electronic transformer interface standards urgently need to be unified
Oct 28 , 2020
New electronic transformers have been developed and applied in our country for more than ten years, and more than 300 power stations have been tested or officially operated. The number of domestic units engaged in the research and development of electronic transformer technology has increased to more than 30, and some or all series of manufacturers have been close to 10. At present, in addition to...
