Power Transmission & Distribution Trainer (Model: XPO-SPS/TLD)

Rated 0 out of 5

Introducing the Power Transmission & Distribution Trainer (Model: XPO-SPS/TLD), a comprehensive setup designed for the study of transmission lines, distribution transformers, and protection systems. Ideal for studying short and long-line Pi models, Ferranti effects, load regulation/efficiency calculations, as well as symmetric and asymmetric fault studies. Covers the protection of transmission lines using a multi-function numeric distance protection relay and the protection of distribution transformers using a multi-function numeric transformer protection relay. Protection relays are connected to RTU/SCADA over RS485, enabling the display of fault records on the SCADA screen for enhanced monitoring and analysis. Equipped with an emergency stop mushroom switch featuring a security key lock on the profile rack, ensuring operational safety.

SALIENT FEATURES
