What role can the reactor play
Sep 18 , 2020
Reactors are also called inductors. When an electrical conductor is connected to the power supply, it will cause an electromagnetic field in a certain space occupied by it. Therefore, all electrical conductors that can carry current are inductive in a general sense. The inductive load must absorb the active current and reactive current of the power grid to operate, so that the power grid can impro...

Analysis and improvement of split core current transformer
Dec 17 , 2020
Split core current transformer, as its name implies, is a current transformer that can be opened and closed on the primary circuit (the side of the measured current circuit, usually a cable or parent card), and is a secondary device by sensing the current on the primary circuit Take measurements or protect relays. In recent years, although the development of China's distribution network has i...

How to choose split core current transformer correctly?
Dec 17 , 2020
Current transformers can be divided into high voltage and low voltage, which are mainly distinguished by the highest voltage of the equipment. Generally, 10KV or more is high voltage, 10KV is medium voltage, and 1kv and below are low voltage. Split core current transformer is mainly used in low voltage, because SCT must be opened and closed, which makes SCT unable to carry out effective sealing an...

Let us learn about these kinds of inductors
Dec 17 , 2020
The inductor will have a blocking effect on the current passing through the inductor under the condition of alternating current. The higher the frequency of the inductor, the greater the blocking effect. This type of condition is called inductive reactance and is measured in ohms (Ω). Said. Inductor characteristic 2: The current passing through the inductor will not change suddenly, the current wi...

Talk about why inductance can eliminate EMC
Feb 27 , 2021
Filtering power capacitors, common mode inductors, and magnetic beads are common shadows in the power supply circuit of EMC design schemes, and they are also the three major artifacts for solving interference signals. Regarding the effects of these three in the power circuit, I firmly believe that many technical engineers do not understand. The content of the article analyzes the basic principles ...

Be aware of these tips when using inductors
Feb 27 , 2021
The main uses of RF inductors are diverse, and can be used in various structural features to consider performance testing schemes for special applications. Matching, resonators and choke coils are the main common uses of inductors in RF power circuits. Matching includes removing the characteristic impedance mismatch and minimizing the reflective surface and loss of the middle route of power circui...

Analysis of the basic knowledge of these two current transformers and the difference between the two
Aug 12 , 2021
1. Bus-type current transformer and pillar-type current transformer Transformer I was asked a question by someone the day before, what is the difference between a bus-type current transformer and a pillar-type current transformer? At that time, there was some confusion, let alone the difference. I still don't have any idea what these two forms look like. After checking the materials, I found that ...
