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.

Generally the power is transmitted in 3-Phase DELTA
circuit. where as lighting is conneted to single phase. and
lighting load is totally unbalanced so a delta circuit
cannot be used in supllying a lighting load due to non-
availability of neutral conductor.
for this purpose a lighting transformer is used which
transforms the 3-phase delta circuit into a 3-phase star
circuit. which can be used to supply single phase
unbalanced loads due to the availability of neutral wire.
the transformer can be used in transforming any voltage

Answer / manish parekh
My plesure to share my knowledge about lighting traansformer.
1.lighting system is not critical system which lead to loss production. So its better to install lighting transformer to isolate the earth fault of lighting distribution system from main Distribution system......primary i/p is delta and Sec o/p is star which also help to lead unbalanced lighting load without effect on main distribution system.......

Lightings tarnsfoemer used when we have no Neutral Neutral point in Secondary side.
And Second think is that when fault current also Limit By this transformer

Answer / sreedarsh.b
Lighting transformers are used to transfer electrical energy from one circuit to another. it is used in elevating the level of voltage before transmitting across long distances.
Light transformers are some of the most efficient and effective electric devices as they are known to successfully transfer 99.75% of the total energy input to the output junction.

why neutral and earth should not be connected on 3 phase 440v/50c/s supply at consumer side. where as on 25kv/ac/50c/s railway traction substation neutral and earth will be connected and track at substation. and track will act as neutral and earth. Reasons for this is needed urgently
