Electrical Engineering has evolved over years so have we. At BESST, we keep pace with technological transformation in the industry. Hence, we provide a wide range of integrated Electric System Design across multiple industries. Our team consists of engineers with experience in various domains and support the development of detailed electric system adaptable with low, medium, and high voltage applications. We can competently handle both your Primary and Secondary electrical design requirements.
BESST ETAP system studies capabiities
BESST uses ETAP (Electrical Transient Analysis Programme) for power system studies. ETAP is a fully integrated AC and DC electrical power system analysis tool. Power system studies are important in determining the safety of the electrical system. The power systems study will identify any equipment which may be overloaded or under-rated. It will identify areas where the system may not operate within regulatory limits. It will provide an ARC FLASH analysis, which is important for determining the best work place health and safety procedures that can be applied.
Primary Electrical Design - what we offer?
Primary electrical design determines the specification, layout and arrangement of all the major equipment in the substation. Our primary engineers will coordinate the other disciplines and ensure that the final design has the look and operation that you are after. We offer:
-
Layout section design
-
Fitting selection as well as fitting design to suit
-
Equipment specification to all relevant Australian Standards
