Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Analyse a range of electrical earthing methods and predict fault currents under balanced and unbalanced conditions.
LO2 Evaluate protective measures and equipment for the utilisation end of the power system and design protection schemes for a range of installation types.
LO3 Evaluate switchgear equipment in the context of international standards and specify appropriate equipment for a range of installation types.
LO4 Use appropriate software for power system analysis, fault calculation and protection coordination.
LO5 Create sample designs for switchgear assemblies based on key data and produce appropriate documentation.

Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
