What is lighting transformer and why its used in industries

Lighting transformer used in industries

Fig: Type of Lighting Transformers

Lighting Transformers are designed to supply power to lighting equipment in a commercial / industrial / domestic unit. Its primary supply connected to higher voltage source and secondary is to be connected to load.  

Lighting transformers serves as isolation between primary and secondary, it also restricts any high voltage spikes and EMF coming with the raw mains incoming power. It also restricts short circuit current in the load and saves major accidents.

It is also used where incoming supply is 3 phase 3 wire and lighting load is 220 Volt single phase.

Power House lighting transformers are made with CRGO laminations and Electrolytic copper super enameled winding wires.

They are available for wide range of inputs out are in the range and in capacity from 15 VA to 50 KVA.

Lighting transformer used only for lighting purpose. As power transformer used for providing power like motor, heater, UPS, chiller, grinder, welding machines, and other electrical equipment other than lighting and lighting transformer are used only for lighting purpose.

Benefits of lighting transformer

 As lighting transformer having tap changing facility we can adjust secondary supply voltage.

By using lighting transformer life of electrical equipment increased (bulb, tubelight, etc ).

As the lighting transformer work as isolation transformer the system is safe from voltage spikes.

Providing lighting load through lighting transformer is much better and safe than providing through power transformer.
