POWER TRANSMISSION & DISTRIBUTION TRAINER

Salient Features
• This setup is used for transmission line study for short as well as long line PI model, ferrenti effects, load
regulation/efficiency calculations, symmetric/asymmetric fault study. This setup also covers protection of transmission
line for distance protection using multi function numeric distance protection relay and distribution transformer protection
using multi function numeric transformer protection relay.
• The protection relays are connected to RTU/SCADA over RS485 which display all fault records on SCADA.
• Emergency stop mushroom switch is provided with security key lock on the profile rack.
• Facilitates easy and safe wiring by students due to use of 4mm sturdy Shrouded banana patch cords and shrouded socket
arrangements for high voltage circuits
• Each panel has ABS molded plastic sturdy enclosure, and colorful screwless overlays showing circuits diagrams & its
connection tag numbers for easy understanding and connection
• Set of Instructor Guide & Student Workbook.
