A three-phase heater with given resistors is connected to the $230~\rm V$/$400~\rm V$ three-phase system. The heater shows purely ohmic behavior and can be configured in wye or delta configuration. \\ | A three-phase heater with given resistors is connected to the $230~\rm V$/$400~\rm V$ three-phase system.
