Introduction to Compact Substation
A compact substation is an integrated electrical equipment that combines high - voltage switchgear, transformers, and low - voltage distribution devices in a pre - fabricated, compact enclosure. It is designed to reduce the footprint, simplify installation, and improve the reliability of power supply. Compact substations are widely used in urban areas, industrial parks, residential communities, and other places where space is limited and a reliable power supply is required. They can transform high - voltage electricity into low - voltage electricity suitable for end - users, and at the same time, provide functions such as power distribution, protection, and measurement.
