TRALIN computes conductor and cable parameters, electrostatic and electromagnetic induction effects on ungrounded conductors, scalar potential, magnetic field and electric field in the air. TRALIN can be applied to both distribution and transmission lines with any number and type of conductors. TRALIN is one of the main engineering modules that drive the MultiLines+ and Right-of-Way software packages.

Extensive conductor databases

Available conductor types for conductor cores

Technical Highlights

• Using TRALIN, you can compute Maxwell potential coefficients, shunt capacitances, self and mutual impedances, and admittances for all conductors on a per-conductor basis and/or a per-phase basis, with skywires or static wires being eliminated or treated as distinct conductors, at your option.
• TRALIN takes into account power frequency, skin effects, and earth characteristics. Specify the thickness, resistivity, permeability, and permittivity of any number of horizontal soil layers.
• TRALIN can accommodate any arrangement of conductors: pipe-type cables, pipelines, solid, hollow, stranded and composite conductors, insulated and bare conductors, overhead and buried conductors, and irregular phase configurations. All cable conductors can have a core, sheath, armor, and arbitrary insulations.

Technical Features

• TRALIN can determine the AC scalar potential and the electric field. These are computed using an original and accurate method called the "Strip Charge Simulation" method. Computations can be made at any set of points both aboveground and below, both on conductor surfaces and elsewhere.
• TRALIN can calculate the magnetic field at aboveground observation points.
• TRALIN can calculate the AC radio noise generated by transmission lines at aboveground observation points.
• Compute the magnetically induced voltage resulting in one ungrounded conductor based on the currents you specify for the other conductors in the system under analysis. Also compute the electrostatic potential induced in one conductor due to the potentials you specify on the other conductors in the system.
• For overhead conductor arrangement with little regularity, conductors are specified one at a time and may be completely different from one another.
• For regular overhead conductor arrangements, conductor characteristics are specified on a per-circuit basis and phase bundle configuration is specified to reduce data entry time.
• For systems which include buried conductors such as pipelines and pipe-type cables, conductors are specified one at a time and may be completely different from one another.
• An extensive conductor database is available to ease input operations.
