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...

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...

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...

Realization of current detection in automobile electronic system
Aug 12 , 2020
Here mainly introduces the detection method of electric current, find some factors that are easy to be neglected in the design. First consider two different methods: the detection method based on the magnetic field and the detection method based on the shunt. 1. Magnetic field-based detection methods (represented by current transformers and Hall sensors) have many advantages, such as good isolatio...

Error analysis and calculation of current transformer
Aug 06 , 2020
First of all, the current transformer is an instrument and equipment that converts a large current into a small current on the secondary side according to the principle of electromagnetic induction. The current transformer is composed of a closed iron core and windings. Its primary winding has very few turns and is stringed in the path of the current that must be measured. Then today I will give y...
