CONTAINERISED SOLAR SUBSTATION
CONTAINERISED SOLAR SUBSTATION
Containerised solar substation are designed for clustered solar parks where space and safety is a concern, and are of capacity 500KW to 20MW projects. Containerized substation is divided in three section or compartment— MV Breaker, Transformer and Inverters with DCDB. Containerised substations are designed in accordance with IS 14786 / IEC 61330 standards with degree
of protection upto IP 43 for Transformer and Inverters compartments & upto IP 54 for MV breaker compartment.
Following are the dimensional and weight details for a typical11kV, Containerized substation with off circuit type Dry / Oil Cooled Transformer.
