Goa has an established 33kV sub-transmission and distribution network.<\/p>

The Electricity Department, Government of Goa, publishes information on substations and associated feeders and identifies numerous 33kV systems and 33\/11kV substations across the state. Its published network information includes 33kV infrastructure associated with locations including Tivim, Kadamba, Verna, Xeldem, Bicholim, Mapusa, Margao, Canacona and other areas.<\/p>

The Government of Goa also publishes a power-line network map covering 33kV and above<\/strong> infrastructure.<\/p>

This makes 33kV switchgear and substation equipment relevant for:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
