Must a 22KV Switchgear step-down with a 22KVA trasformers?

A 22 kV switchgear does not necessarily need to step down using 22 kVA Transformers. The switchgear can be used in conjunction with transformers of various ratings depending on the load requirements. The transformer rating should match the load it serves, and the switchgear is designed to handle the voltage and current levels of the system. Therefore, the choice of transformer depends on the specific application and load characteristics rather than being strictly tied to the switchgear voltage.
