Case Studies

We provided research and development (R&D) consulting services, as well as aiding in the redesign of major sections of the Fastec START product. We helped to combine the various incomplete and undocumented design revisions into a working, fully documented and manufacturable product. This product in particular required an engineering firm competent in Power Electronics, Software and Electrical engineering, making B Duncan a perfect fit.

Fastec START Project

We were approached to help commission new reclosers for upgrading the overhead network’s protection of the electrical supply at Macres Mine. These protection devices were installed on their overhead 11kV lines, which were used for both ring networks with directional protection running and radial networks with standard over current protection.  This upgrade enabled the system to clear faults, improving its reliability.

B Duncan LTD provided third party design review services for a major electrical power systems manufacturer to improve the electrical reactive and real power calculation accuracy of a power system measuring device. After our review, a unique solution was proposed and implemented in software, resolving the existing measured distortion. This was deigned at no extra cost to system resources, a major requirement for the client.

The advantage of working with B Duncan Ltd was that we did get a software solution we were able to use in our system straight away without having to modify it. A clean and tailor made implementation.

“Barrie has acquitted himself to the highest standards. I have absolutely no hesitation in recommending Barrie for any vocation that he chooses in the future. As a software engineer Barrie quickly became the team “go-to” person and was tasked with leading several critical projects, in which he delivered above expectations. As testing team leader, Barrie led his team to greatly improve the quality and quantity of testing for our controller products.”
