Double Bus Bar Trainer (Model: XPO-PET/DBB)

Rated 0 out of 5

Introducing the Double Bus Bar Trainer (Model: XPO-PET/DBB), a comprehensive educational tool designed for in-depth studies in bus bar operations and load flow scenarios. The trainer facilitates the study of bus bar operations in both 3 and 4 bus load flow scenarios, encompassing ring and radial bus studies. It serves as a practical learning platform for understanding grid and power station operations. A table-top modular station with 9 switching bays, the trainer is equipped to address the operational requirements of both the grid and power station. It represents two bus bar segments, allowing students to learn interlocking conditions for safe switching operations. Employing two sets of 3-phase board supply using EMT1 panels, each consisting of protection MCB + O/L relay, the trainer simulates two generators to replicate interconnected distribution systems realistically.

SALIENT FEATURES

Facilitates study of bus bar operation in 3 and 4 bus load flow study, ring, radial bus study.
Table top modular double bus bar switching station with 9 switching bays. It is equipped in such a way that the requirements of the both the grid and the power station operation are dealt in practice oriented way. Two bus bar segments are represented. Here the interlocking conditions in a switching station can be learned in order to conduct safe switching operations, as the situation requires, on the grid and power plant.
Employs 2 nose of 3 phase board supply using EMT1 panel consisting of protection MCB + O/L relay to simulate 2 generators to simulate interconnected distribution system.
Optionally PC based SCADA software (XPO-VWB) provided for online graph plotting & data acquisition mode, 16 nos. of DPM screen to display numerical values for voltage, current, watt VAR etc.
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 moulded plastic sturdy enclosure, and colourful screwless overlays showing circuits diagrams & its connection tag numbers for easy understanding and connection.
Set of Instructor Guide & Student Workbook.
