Home / Relay Protection of Main Step-Down Substation
The operation and equipment for this system are the same as those of the direct underreaching system, with the addition of fault-detector units at each terminal.
This module is used to introduce trainees to step down transformation from 380 VAC to 208 /VAC, in addition to controlling loads buses (loads transfer and bus coupling) using isolators and circuit breakers.
