From Wikipedia, the free encyclopedia. The IEC Technical Committee 57 Uec Group 03 have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems.
The standard is suitable for multiple configurations like point-to-point, star, mutidropped etc.
