Principle Vision of Our Company

RBJ Engineering Corporation is founded on the principles of hard work, dedication, and cooperation with our customers to achieve environmentally responsible and timely delivery of quality solutions to meet any transmission system need. Together we forge the future.


RBJ Engineering Corporation has extensive experience in all aspects of power systems studies and high voltage transmission system engineering in HVDC, EHVAC and Dynamic Reactive Compensation. We offer comprehensive engineering services in the following areas:

Transmission System Studies

Specifications and Bidding

Management and Administration

Testing and Commissioning

Specialized Software

Development of unique software solutions is a core competency of our business. This includes calculation tools for the analysis and design of ground electrodes, AC and DC filters, and harmonic current and voltage calculations from LCC, PWM VSC, and SVC converters.

Electrode Surface Potential Rise and Voltage Gradients

The electrode program calculates voltage profiles and voltage gradients in the conductive media around electrode sites. Earth and sea water near the electrode represented by a resistive matrix representing three dimensional volumes of uniform resistivity within a cylindrical shape around the electrode site. The program is capable of modelling land, sea and shore electrodes. Features include:

  • State of the art boundary element analysis
  • Sparse matrix methods allowing more than 14 million nodes
  • 2D and 3D Output Plotting
  • Non-symmetrical electrode shapes
  • Individually definable resistivity for each volume element

Direct calculations using analytical expressions are usually used for calculation of step potentials and current density at the electrode-soil boundary. However, such methods are not sufficient if the soil in the immediate area of the electrode is not uniform. In such case the soil structure near the electrode can be modelled in detail in using the program to establish the expected variation in step voltage or current density. The program has been extensively compared and benchmarked against exact analytical methods on simple symmetrical configurations.

Typical investigations involve determing the potential interference with other buried facilities.

The program has the capability to model very large soil structures, to distances in excess of 100km from the electrode site. The size of the model and level of detail would be selected based on the soil data and the objectives of the investigations.

Ground Electrode Program

Electrode Dynamic Temperature Rise Program

This software is designed to predict dynamic temperature rise and cooling of ground electrodes due to specific DC current injections. This is accomplished by means of a 2D Fourier heat flow algorithm.

Harmonic Analysis Programs for AC & DC

Our software allows us to determine voltage and current harmonics from HVDC and industrial power electronic converters. This allows both design and verification of filter performance and ratings when the system harmonic impedance is known. Our capabilities include:

  • Calculation of system harmonic impedances under multiple operating conditions with mapping to a region in the RX-plane
  • Flexible modelling of any filter configuration
  • Consideration of filter component tolerances, environmental tolerances, and system frequency variations

AC Systems and Filter Configuration

Electric and Magnetic Field Calculations

Our software solution provides the ability to analyze complex tower and conductor configurations, including AC and DC on the same tower or same right-of-way. Typical analyses are:

  • Conductor surface gradients on AC and DC conductors in the same tower
  • Static and Enhanced electric fields from DC lines
  • Ion current flow and ion current density near ground-level
  • Magnetic fields from DC lines or cables, with simultaneous consideration of the earth's magnetic field
