ARSON Engineering’s Design Department is involved in planning, analysis, and detailed engineering of electrical substations. Substations play a crucial role in the power distribution system by transforming voltage levels, distributing power, and ensuring the reliable and efficient operation of electrical grids. Design work for Grids and Sub-station are divided into Primary and Secondary Engineering. Primary Engineering deals with Site Surveys, Layouts finalization, conceptional drawings, Outline drawings along with Equipment selection & basic design finalization. Secondary Engineering deals with SLDs, Schematics, Cable scheduling, Relay logics etc.

Both primary and secondary designs are interconnected and need to be coordinated to create a seamless and reliable power grid. The integration of advanced technologies, adherence to standards, and consideration of future expansion are crucial aspects of a comprehensive grid design. Engaging with experienced electrical engineers and grid planners is essential for the successful implementation of these designs.
