The Transmission Line Simulator investigates single-phase and three-phase transmission lines.
The configurable simulated transmission lines allow realistic studies of short, medium and long-distance transmission lines under variable load and power factor conditions, as well as with inserted faults.
The console is divided into two control panels, each with detailed mimic diagrams.
The upper panel has a single-phase transmission line equivalent circuit, and the lower panel a three-phase transmission line.
The lines may be loaded by the resistive, capacitive and inductive loads included.
The effects can be monitored by instruments at the send and receive ends of the transmission lines.
The single-phase transmission line includes a set of inductive impedances connected in series.
Tapping points allow the user to: change the length of the simulated line;
Set up Pi or Tee methods of loss profiling using different values of capacitance; and monitor the voltage, current and power at any point along the line.
The three-phase transmission line is in six sections represented in per-unit values.
Facilities include: Operating under variable balanced or unbalanced RLC (resistive, inductive and capacitive) loads
Selectable neutral Provision to vary the length parameters
A fault application switch and earth fault resistors allow studies of earth fault currents and the operation of relays of varying sensitivity.
For protection tests, current transformers (CTs) in the test circuits connect to the protection relay fitted to the control panel.
