What Is Electromagnetic Interference (EMI)?
EMI is interference caused by electromagnetic disturbances that can affect the performance of equipment. The source of EMI can be environmental factors such as electrical storms and solar radiation, but a more common source is other electronic equipment or electrical systems. EM interference often manifests itself in the form of undesirable noise that may cause functional interruption of electrical systems, electronic systems, and RF systems.
Common Sources of EMI
- Power generation equipment and its peripherals such as generators, power supplies, voltage regulators, switches and relays, battery chargers, and high voltage transmission lines.
- Equipment operating at high frequencies, such as oscillators, computing equipment, radios, radar and sonar equipment.
- Machines operating at high voltages and high frequencies, e.g. electric motors and ignition systems.
