conducted interference的意思|示意

Conducted interference is a type of electrical noise that is generated inside electronic equipment and then conducted by electric cables or wires connected to the equipment. It is most commonly seen in power and signal cables. Conducted interference can be caused by electrical current flowing through the equipment itself or by external sources, such as motors and electric power lines.

Conducted interference can cause errors in electronic data transmission, reduce the accuracy of data, and create errors in computer programs. To prevent interference caused by conducted interference, shielding is used to reduce the amount of interference that is conducted by the cables.

Conducted interference can also be caused by electromagnetic radiation, which is emitted by radio and TV transmission towers, cell phone networks, and other sources of radio frequency energy. This type of interference is known as radiated interference. To reduce the effects of radiated interference, shielding and filtering is typically used.

Conducted interference can also be caused by electrostatic discharge (ESD), which is a sudden release of energy from an electric charge. ESD can be caused by static electricity or a power surge. To reduce the effects of ESD, grounding and surge protectors are usually used.

Conducted interference can also be caused by crosstalk, which is a type of electrical noise that occurs when two cables are too close together and the signals leak between them. To reduce the effects of crosstalk, it is important to route cables in a way that keeps them at least 4 inches apart. If two cables must be routed side-by-side, they should be shielded.

In order to reduce the effects of conducted interference, it is important to use proper shielding, grounding, filtering, and crosstalk prevention techniques. By using these techniques, a system can be designed to minimize the amount of interference that is conducted through the cables and wires in electronic equipment.
