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.

Construction Lighting Transformers

Control Transformers are two-winding transformers with both windings made of copper. Power House transformers are made of using high-quality materials.

Electrolytic grade super enameled wire with the best insulations is used. Core materials are CRGO EI or Strip cores. Experienced hands with the best machines for winding ensure the best results with minimum size. Appropriate class of insulation materials are used. Transformers are impregnated in insulating varnish for long-lasting performance. Input and out are terminated on Bakelite board with the proper size of terminals.

The Lightning Protected Transformer virtually eliminates transformer failure due to lightning. An UltraSIL Housed Polymer Evolution arrester or gapless VariSTAR porcelain arrester, designed by Cooper, provides overvoltage protection. Cooper’s STORM TRAPPER high-energy arrester, a low-voltage distribution arrester, is mounted directly to the transformer’s secondary windings, protecting the transformer from failures caused by secondary-induced surges. A properly coordinated D-Link fuse by Cooper provides superior over-current protection.
