|Description:||This module will examine low, medium and high voltage systems in a power systems context. |
|On successful completion of this module the learner will be able to|
- Select suitable equipment relating to the planning of electrical installations in the context of high voltage (HV), medium voltage(MV)and low voltage (LV) systems.
- Describe the factors relating to low voltage (LV), medium voltage(MV)and high voltage (HV) substation siting, planning and plant layout.
- Describe the construction, principle and use of electric machines, and carry out steady-state performance
- Explain the function, operation and safety requirements for high voltage (HV), medium voltage(MV)and low voltage (LV) systems
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 CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
|No recommendations listed|
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
|No incompatible modules listed|
This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
