Gas Insulated Substations: Gis - M. S. Naidu - Google Books· Conventional substations using atmospheric air as the main dielectric cannot satisfy these requirements, but totally enclosed substations using sulphur hexafluoride (SF6) gas insulation that are also known as Gas Insulated Substations (GIS). GIS is now in widespread use in the electrical power industry, especially in metropolitan areas.5/5(2)
High Voltage Testing· PDF filetransformer used would have to have a current rating. It is thus normal to subject the cable (soon after laying it, but before energising it ) to carry out a high voltage test under d.c. conditions. The test voltage would be about 2 (working voltage ) and the voltage is maintained from 15 min to 1.5 hrs. This d.c test is not complete equivalent
