Power disturbances as EMI problems. (electromagnetic interference) (The Designer's Guide to Electromagnetic Compatibility)(includes related article on developing a power specification) (Tutorial)

EDN, January, 1994 by Kimmel, Bill

Power disturbances are often orphans of the EMI world. The equipment designer blames the power company, the power company blames the installer, and the installer blames the equipment designer. Meanwhile, it's often the user who is fouling his or her own nest by polluting the local power. One study showed that local pollution caused more then 85% of the power problems. Incidentally, as consultants, we are seeing an increase in power-disturbance problems, and we believe power disturbances will be a growing EMI problem in the 1990s.

Rather than point the finger, we all need to work together to prevent and to solve these power-related EMI problems. As design engineers, we need to build in more protection against power disturbances. We also need to...
