    What is the difference between system voltage & equipment voltage.

    In 33/11 kv substation, for 33 kv system voltage we are taking 36 kv as equipment voltage for VCB bt in case of LA we use 30 kv as equipment voltage.why? what is the design consideration for deciding the rating of equipments?
