Electric power is necessary for modern life. Companies must understand power issues to protect their computer systems. When clean power is used, there is no interference or voltage fluctuation. What is the proper term for line noise?

Question

Quizplus · Accepted Answer

The proper term for line noise is electromagnetic interference. Electromagnetic interference is disturbance to the flow of electric power while it travels across a power line. Electromagnetic interference can be created by the difference between three wires: hot, neutral, and ground, and the magnetic field they create. Lightning and electrical motors can induce electromagnetic interference, which could then interrupt the proper flow of electrical current as it travels over wires to, from, and with buildings.
