RE: LTC and transformer ratings
...as the number of secondary turns is reduced when the voltage is lowered, the primary current will be higher for a given secondary current. This will increase the I2R losses in the primary. The manufacturer may derate the transformer somewhat more than the reduction in KVA estimate. Or not, depending on their design margins.
