Structural Configuration
A standard 500 kVA compact substation is divided into three isolated compartments for safety and functionality:
1.Medium Voltage Section
Equipped with SF6-insulated RMUs or load break switches, this compartment handles incoming MV power (typically 11 kV or 22 kV). Safety features include surge arresters, current transformers (CTs), and interlocks.
2.Transformer Chamber
This compartment houses the 500 kVA transformer, built with high-grade CRGO silicon steel core or cast resin technology. Thermal indicators, oil level gauges, and pressure release valves ensure safe operation.
3.Low Voltage Section
Outgoing feeders, typically via molded case circuit breakers (MCCBs) or air circuit breakers (ACBs), distribute power to the connected loads. The panel includes voltmeters, ammeters, energy meters, and optional IoT-based smart monitoring.
Typical Applications
- Residential Developments
Ideal for apartment blocks, townships, and gated communities where footprint is limited. - Industrial Units
Suited for light manufacturing facilities and small-scale factories. - Solar Power Projects
Converts and distributes power from solar inverters to the main grid. - Commercial Zones
Used in malls, office parks, and schools for secure, efficient energy delivery. - Public Infrastructure
Deployed in metro stations, hospitals, and data hubs for uninterrupted service.
