WebThree Phase A three phase transformer is designed to transform a three phase input (source) voltage to the single phase and three phase output (load) voltages required by your equipment. In order to select the correct three phase transformer you must first determine: 1) The equipment being installed operates on a three phase supply. WebFor Transformer, we should choose two types of cable such as the primary side and secondary side. The rating of the cable should be 150% of the full load current. i.e if your transformer’s primary current is 450 Amps means, you should choose 450 *150% = 675 Amps capacity size cable. WebJan 5, 2024 · A step-down transformer is an electrical device that reduces the voltage of an alternating current ( AC) power supply.
