2) a) High voltage (HV) power transformer with the rated voltage 100 kV and above usually used liquid dielectric as insulation media. i. List down two type of liquid dielectrics that widely used in HV transformer as insulation media and describe why these liquid dielectrics is utilized in this apparatus. ii. Name two type latest development of liquid dielectrics that have been utilized as biodegradable liquid in HV transformer. Discuss why biodegradable liquid dielectric become very significant in nowadays compare with conventional liquid dielectric? b) There are six greenhouse gases emissions contribute to the global warming issues that have been declared in the Kyoto Protocol. i) Name one of the greenhouse gases that currently utilized in gas insulated switchgear (GIS). Explain why it used in this apparatus? ii) Describe how this greenhouse gas emission could be minimized in GIS?
