lighting transformer is a transformer witch is required for lighting load near to supply source end to limit the fault current due to very low impedance near the main source. it also reduce the high voltage spikes & EMI in the primary to transfer in the secondary.It also used where the primary supply is 3-phase & 3-wire to get neutral point in secondery.
