IED for Substation

An Intelligent Electronic device is a term used in the electric power industry to describe microprocessor-based controllers of power system equipment, such as circuit breakers, transformers and capacitor banksetc. The IED are based on IEC61850 communication standard.
Measurement IED is used to measure threephase Currents, three phase Voltages, Power, Active Power, Reactive Power, Power factor, Energy etc.The IED publishes datausing MMS (Manufacturing Message Specification) Publisher and receives data from Merging Unit using SMV Subscriber
