Electrical Power Systems Safety
Overview
This unit of study aims to introduce electrical safety standards, fundamentals of electrical safety, earthing systems and electrical insulation under high voltage. The protection measures of overvoltage, residual voltages and leak current in power systems is also provided. Furthermore, the application of electrical safety in special locations and installations is discussed.

Learning outcomes
Students who successfully complete this unit will be able to:
- Apply fundamental concepts of electrical safety to identify safety issues in power systems (K1, K3, S1, S2)
- Appreciate safe measures and protection devices in an environment that may contain potential electrical hazards (K1, K3, S1)
- Collect and analyse experimental data, interpret results, formulate conclusions and generate laboratory reports (K1, K2, S1, A2)
- Use computer simulation tools to analyse electrical field strength in high voltage systems leading to the proper selection of insulation materials (K1, K2, K3, S1, S2)

Hurdle
As the minimum requirements of assessment to pass a unit and meet all ULOs to a minimum standard, an undergraduate student must have achieved:
(i) an overall mark for the unit of 50% or more, and(ii) at least 40% in the final exam, and(iii) must complete all laboratory workStudents who do not successfully achieve hurdle requirements (ii) and (iii) will receive a maximum of 45% as the total mark for the unit.
