Generation Trainer with Protection Relays (Model: XPO-PRT/GEN)

The Generation Trainer with Protection Relays (Model: XPO-PRT/GEN) is a cutting-edge educational tool designed to provide a hands-on experience in understanding power generation systems and their associated protection relays. Transparent Construction: The conservator and transformer tanks are crafted from transparent acrylic, enabling easy observation of oil levels. This transparency facilitates a clear view of the internal components, enhancing the learning experience. Simulation Tools: Included in the trainer are both an air pump and a foot pump to simulate gas formation and short-circuit faults. The Quick Release Coupling (QRC) socket allows for the easy replacement of the air pump with the foot pump, offering flexibility in simulation methods. Observation Features: Transparent piping is integrated to enable easy observation of oil flow and air bubbles, providing a visual representation of the generator’s operation and potential issues.

SALIENT FEATURES

  • Facilitates generator protection using numerical generator protection relay.
  • VFD drive used to control brushless prime mover’s speed in manual mode.
  • Multi function meters read the input voltage & frequency of generator output along with power analyser data. (optional)
  • The Generator/ alternator coupled with prime mover have brought out six terminals from three phase 3 windings (RYBs). The every alternate terminal of RYB is shorted and connected together to form Star connection (Neutral) at the output of generator.
  • The relay panel carries shrouded sockets to connect Generator Protection relay mounted below. The CT panel and PT panel provide necessary interface between real world & relay.
  • 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.
