Answer Posted / h r jadhav
when line voltage 480 is used across the primary of step
down trf having secondary is 230 volts then 1 phase motor
will load same current to lv side however it will load the
primary with respect to tf ratio. so if u have tf rated 10
amp for primary it is welland good.and if it is for
secondary it is well.
