Abstract
Copper busbar conductors are an integral part of any high current switchboard. A suitable switchboard design must be capable of withstanding the mechanical, electrical and thermal stresses which are likely to be encountered in normal service. The aim of the project is to simulate and model, in Matlab, the operating temperature of various current carrying copper busbar conductor arrangements in a specific bus zone and to assist with design selection to Australian Standards.
The project objectives, detailed in the dissertation, list several milestones to achieve the project aim. The objectives can be summarised into three categories:
1. Research
2. Matlab Script Development
3. Testing
Although three distinct categories, a continuous cycle of all three was implemented throughout the project to generate acceptable results.
The developed Matlab Script is able to produce plots that contain operating temperature curves for a given current and ambient temperature. This provides another method for switchboard manufactures to determine busbar current carrying capacities within the specific enclosure. The accuracy of the curves are within ±8% when compared with the AS 3000:1991 method, which is also an approximation, and within 1% error when compared with the real test results (Type Tested) for the specified enclosure at a single point.
