Location of the Vietnam power distribution box

Power distribution boxes in Vietnam are generally located at substations, industrial facilities, and local utility points managed by Vietnam Electricity (EVN), with schematic maps available for rough locations.

Overview of Vietnam's Power Distribution System

Vietnam Electricity (EVN) is the state-owned monopoly responsible for electricity transmission and distribution across the country, operating under the Ministry of Industry and Trade (MOIT) and supervised by the Electricity Regulatory Authority of Vietnam (ERAV) for planning, licensing, and tariff regulation . The national grid is divided into North, Central, and South regions, interconnected by high-voltage transmission lines, including the 500kV North-South line . Distribution boxes are installed at substations, industrial plants, and local distribution points to manage the flow of electricity from high-voltage transmission lines to end users .

Industrial and Hybrid Distribution Boxes

In industrial settings, such as factories in Ho Chi Minh City, AC/DC hybrid power distribution boxes are used to integrate the EVN grid with local renewable energy sources like solar PV arrays. These boxes include Automatic Transfer Switches (ATS), DC breakers, and Surge Protective Devices (SPDs) to ensure safe and reliable power distribution . They are typically installed inside factory electrical rooms or near substations and are engineered to prevent overloads, short circuits, and back-feeding into the grid .

Mapping and Schematic Resources

While exact locations of all distribution boxes are not publicly disclosed, schematic maps of Vietnam's transmission and distribution network are available through datasets prepared for projects like the World Bank's Second Transmission and Distribution Project . These maps provide rough locations of substations, transmission lines, and distribution points, which can be used for planning or research purposes. Additionally, platforms like Open Infrastructure Map offer open-source maps of electricity infrastructure, including substations and major distribution nodes .

Key Points

• Managed by EVN: All distribution boxes are under the operational control of Vietnam Electricity .
• Locations: Found at substations, industrial facilities, and local utility points.
• Integration: Some boxes, especially in industrial areas, integrate renewable energy sources with the national grid .
• Mapping: Publicly available schematic maps provide approximate locations but not precise GPS coordinates .

For practical purposes, if you need to locate a distribution box for industrial or maintenance purposes, contacting EVN regional offices or consulting schematic network maps is the recommended approach.
