Transmission Line Simulator
Product Code : EL-EPP-11356
Quick Answer: The Transmission Line Simulator investigates single-phase and three-phase transmission lines on a two-panel console with detailed mimic diagrams. Its configurable simulated lines let students study short, medium and long lines under variable load and power factor, and with faults inserted.

Key Features
- Upper panel: single-phase line equivalent circuit of series inductive impedances, with tapping points to change line length and monitor voltage, current and power along the line
- Pi or Tee loss profiling using different values of capacitance
- Lower panel: three-phase line in six sections in per-unit values, with selectable neutral and variable length
- Resistive, capacitive and inductive loads included, for balanced or unbalanced loading
- Instruments at the send and receive ends of each line
- Fault application switch, earth fault resistors and current transformers connected to a protection relay on the panel

About This Product
Students set up a line of a chosen length, load it and compare sending and receiving end readings to see voltage drop, losses and the effect of power factor. Applying earth faults through different resistances shows how fault current relates to relay sensitivity.
Frequently Asked Questions
Can the line length be changed on the Transmission Line Simulator?
Yes. Tapping points on the single-phase line change the length of the simulated line, and the three-phase line has provision to vary its length parameters.
Are loads included with the simulator?
Yes. Resistive, capacitive and inductive loads are included for loading the lines.
