As Consulting Electrical
Engineers specializing in Electrical
related areas, we provide a full range of field measurement, design and analysis services related to the
grounding of electrical transmission systems, pipelines and industrial
plants. As well, we perform ground electrode model analysis and grounding
* "Grounding" is a North American term. In other parts
of the World, it is often called "earthing".
We have developed a specialized expertise in grounding system
measurements, including soil resistivity studies, electrode
resistance measurements, the investigation of the integrity of large
grounding systems, and measurement of grounding in patient care
installations and are fully conversant with the problems inherent in
carrying out the field measurement of grounding parameters.
- We have pioneered the technique of
using a variable frequency power source and frequency selective
voltmeter to conduct measurements on large grounding systems in the
presence of high ambient electrical interference and have a good
understanding of the ac component of ground systems and inductive
coupling errors that may occur in measurements.
We have developed software that enables us to carry out the complex
calculations required in the design and analysis of grounding
systems. These calculations include power system analyses required to
determine ground potential rise, calculations to determine step and
touch potentials, and calculations related to effects of induction and
ground currents on pipelines. We have provided this software to
others for their own use in analyzing grounding systems. Present
versions of our software run on computers with Microsoft Windows
- We are based in North Vancouver, British
Columbia, Canada and maintain a sophisticated range of facilities,
including field measurement equipment, in-house computers, computer
terminal equipment, and a reference library.
