New intelligent electronic devices change the structure of power distribution systems

With the introduction of new intelligent electronic devices (IEDs), classical disciplines in electric utilities like protection, control, nonrevenue metering, power quality analysis, disturbance recording and automation will come under one responsibility. The IEDs with very high functionality will lead to significant cost savings and offer new problem solving capabilities. With these changes, utility personnel will need extensive training on the new practices, and a close partnership between vendors and utility customers will be necessary.
