The Application of Current Transformer
Feb 20 , 2020
The current transformer is very similar to the transformer. The transformer is mainly used to change the voltage of the line on the line, while the current transformer is mainly used to change the current of the line. There are two types of current transformers for power systems and instruments. Current transformers for power systems are an indispensable electrical appliance in output and power su...

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...

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...

Principle and main function of transformer
Dec 17 , 2020
Current transformer is an electronic component that can convert electrical energy into magnetic energy, store it under appropriate conditions, and release it and then convert it into electrical energy. The most important role of inductor is electromagnetic conversion. All electrical conductors (transmission lines) will cause electromagnetic fields when passing current. When the electrical con...

Inductor selection analysis, let's understand together
Feb 27 , 2021
You should be clear about the scope of inductance in the power circuit. Since the inductance is mostly not stable during the entire working period of the components, it is particularly important to grasp the scope of the effective value. For inductors used in power switching applications, the overall goal of allowable harmonic distortion current and transient response will determine the inductance...

Transformer internal structure transformation ratio conversion method
Aug 12 , 2021
The current transformer is an instrument and equipment that converts a large current on the primary side into a small current on the secondary side for accurate measurement based on the basic principle of the magnetic effect of the current. It is mainly composed of a closed iron core and windings. Transformer The number of turns of the primary winding coil is very small, which is stringed in the r...

Application of Rogowski Coil in Active Power Filtering
Jul 21 , 2022
The extensive application of nonlinear loads in power grids brings a series of problems harmonic wave. The main hazards of harmonic wave include: Increase the load of power facilities, reduce the power factor of the system, reduce the effective capacity and efficiency of power generation, transmission and electrical equipment, resulting in equipment waste, line waste and power loss; Causes th...
