Intelligent electronic devices (IEDs) are one of the most powerful tools in an engineer’s toolkit to improve feeder reliability. They have the ability to isolate outages and restore service remotely to customers in unaffected sections of the feeder, all with a myriad of combinations of time-current characteristic (TCC) curves, features and custom logic. But to realize maximum improvement, the correct device needs to be in the proper location.
The Right Device in the Right Location
Proper placement of intelligent electrical devices improves fault location, isolation and service restoration schemes.
