Unbundling power quality services: technical issues

The modern industrial facility depends on sensitive electronic equipment that can be shut down suddenly by severe power system disturbances. A large number of these disturbances on the power system are a result of line faults which can cause momentary voltage sags. This results in equipment malfunctioning and high cleanup cost. This papers describes some of the emerging opportunities for new services to users of electrical power. In particular the focus is on the need for improved quality of power and methods for providing this new service.
