Control Transformer:

Control Transformers are used in switchgear and controlgear to supply power to control or auxiliary equipment not intended for direct connection to the main circuit. These transformers are specifically designed to provide control supply voltage for the control circuits of AC motor starters, i.e. Starter coils, timers, indicating lamps electronics protection relays etc.

Control Transformers are used in switchgear and controlgear to supply power to control or auxiliary equipment not intended for direct connection to the main circuit. These transformers are specifically designed to provide control supply voltage for the control circuits of AC motor starters, i.e. Starter coils, timers, indicating lamps electronics protection relays etc.

Control Transformers for contractor applications have to Energize the coil and Maintain a contact for definite period of time. The initial energizing of the coil takes 5 to 40 mil seconds and requires 3 to 10 times the normal current. While calculating the VA rating of the Control transformer, this factor should be taken in to account.

Power House control transformers are available for single phase, two winding, with tapping of +/- 5% in input primary side and no tapings on secondary unless specially ordered for. These are Natural air cooled and suitable for mounting within enclosure with switchgear and controlgear assemblies. Control Transformers are available for capacity from 15 VA to 30 KVA.

Construction:
Control Transformers are two winding transformers with both windings made of copper. Insulating material used are class E unless otherwise specified. Power House transformers are made of using high quality materials. Electrolytic grade super enamel wire with best insulations are used. Core material are CRGO EI or Strip cores.

Experienced hands with best machines for winding ensures 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 proper size of terminals.

Quality & Standard:
Power Control Transformers are made as per IS 12021 : 1987.
