What is a 1000 kVA Substation?\n\n\n\n

A 1000 kVA substation is designed to receive electrical energy from a higher voltage transmission or distribution line and convert it to a lower voltage suitable for utilization by buildings, industries, or small grids. The station typically includes:\n\n\n\n

\n
• A medium-voltage incoming line (e.g., 11 kV)\n\n\n\n
• A 1000 kVA transformer (oil-immersed or dry-type)\n\n\n\n
• A low-voltage distribution board (L.V. panel)\n\n\n\n
• Protection and metering equipment\n\n\n\n
• Earthing system\n\n\n\n
• Civil infrastructure (foundation, fencing, room or kiosk, cable trenches)\n\n\n\n\n
