A 11kv gis ais 315 kva mini substation is an electrical facility, which is combined with distribution transformer, primary voltage switchgear and secondary voltage switchgear. The main advange of a 11kv gis ais 315 kva mini substation is the compact designing. It allows the 11kv gis ais 315 kva mini substation could install and run deep into the central area of a city. The following is the function and the main components of a 11kv gis ais 315 kva mini substation:
Controlling units: loading breaker switch, circuit breaker, isolating switch, and earthing switch,etc.
Protecting units: protection relays, surge protectors, and lighting arresters, etc.
Metering and measuring units: current transformers, potential transformers and digital meters.
Reactive power compensation unit:capacity bank, primary harmonic eliminator, SVG, and etc;
