Electrical Power System Trainer: Transmission Line Simulator Model ELTR 026A

Part of the Modular Power Systems range, the Transmission Line Simulator investigates single-phase and three-phase transmission lines.

• Self-contained teaching module, ideal for class and project work
• Part of Sci-tech Modular Power System – can connect to other parts of the system for even more experiments
• Allows realistic studies of short, medium and long-distance transmission lines under variable load and power factor conditions, as well as with inserted faults
• Fault application switch and earth fault resistors allow studies of earth fault currents and the operation of relays of varying sensitivity

Item Description

• Enables ‘Pi’ or ‘Tee’ methods of loss profiling
• Separate single and three-phase line simulations
• Built-in industrial-standard digital protection relay gives wide range of functions – module includes extra socket for additional relay to give more experiments
• Detailed mimic diagram and clear labelling help students’ understanding
• Includes work surface and cable racks for convenient and efficient use
• Includes supplies, circuit protection, internal load banks, instruments and controls
