- To enable students to gain an understanding of general three-phase circuit theory principles, ELV earthing and protection systems.
- Pre-requisites / Co-requisites:
- Students must be admitted to the Bachelor of Engineering Technology programme to enrol in this course. Pre-requisites: ENGGMG5015 or ENGGMG5034.
- Topics include:
1. Star and delta connected three-wire, star connected four wire circuits, three-phase relationships and phase angles
2. Calculations involving a three-wire star load and four-wire star configuration with neutral impedance
3. The power developed in single-phase and three-phase circuits is calculated and analysed
4. Power factor correction calculations are performed on single-phase and three-phase circuits, capacitor values in kVAr and uF for single and multiple circuits, balanced and unbalanced loads
5. Single-phase power, three-phase power, three-phase kVAr
6. Basic components of ELV/LV power system protection (eg, MEN, TT and fuses, MCB, RCD)
7. Parameters on a current interruption oscillogram (ELV)
8. Earthing systems, fault types and detection methods for ELV, LV installations
9. Causes, effects, and mitigation of harmonics in power systems are explained in accordance with NZECP 36:1993 and industry practice with calculations on single phase circuits containing complex waveforms
10. Terms used for electricity loads, calculation of costs of supply at different tariffs, power factor correction effects on tariffs, load control improvement
11. Describe the principles of electrical and building reticulation and outdoor installations as described in the terms of the intent and application of the Electricity Regulations
