Unit Description and General Aims

In this unit students will acquire advanced theoretical knowledge, critical analytical and practical skills which can be applied to investigation and resolution of complex problem solving scenarios. The unit material has been developed to enhance students’ communication skills, individual and group project participation and other professional capabilities important to underground design and construction required in power generation. This unit provides an expert introduction to underground power system design. Students gain specialist knowledge about cable systems, types of system topologies, manufacturing practices and standards. The uses and design parameters of the equipment necessary for underground system design are also addressed. Subsequently, basic underground cable design practices are reviewed and installation practices for both transmission and distribution projects are considered as well as relevant as application concepts such as hydraulic pressures, commissioning and industry standards.
 
Following an underground system case study, students undertake a final assignment replacing a low Pressure Fluid-Filled system and upgrading a High Pressure Fluid-Filled system.
