Biography


Profile

Rajinda is an electrical engineer with 7 years of work experience in power transmission and distribution. He has been involved with several utility, mining, and gas field projects, which include designing substations (primary system and protection) and reticulation, preparing specifications, and project management. He has prepared power and protection single line diagrams, prepared general arrangement, layout and elevation drawings, and drafted several using AutoCAD for substations up to 132 kV. He has been a project manager of 33/11 kV substation projects, 33 kV and 11 kV overhead line projects, 33 kV underground cable installation projects, and 33 kV overhead line condition assessment projects.


He has carried out 11 kV and low voltage arc flash studies. He has designed generator protection, and has carried out earthing tests and earthing studies. He has assisted in condition assessment of 110 kV cables and ancillary equipment, and 66 kV cable installation design. He has carried out load flow studies to construct new 11kV feeders. He has been involved with low voltage reticulation designs for coal mine sites and road lighting, and cable selection and protection coordination in substation low voltage circuits.
