Control Transformers (3 Phase)

Additional Details

These Control Transformers (3 Phase) are basically used for the purpose of converting alternate current from one voltage to another. Transformers could either be step up or step down voltage. Under usual operating conditions, a transformer is a low continuance, long lasting static solid state device with actually no moving parts. In the most unsophisticated terms, it includes 2 or more coils of insulated wire that are wound on a laminated steel core. When the prime coil receives the incoming voltage, the iron core is magnetized and that induces the voltage in the secondary coil. The actual voltage ratio between prime and secondary coils depends up on the turn ration of both the coils.

Control transformers incorporate high-quality insulating materials. This insulation is used to electrically insulate turn to turn windings, layer to layer windings, primary to secondary windings and ground. Control transformers are vacuum impregnated with VT polyester resin and oven-cured, which seals the surface and eliminates moisture. Filling the entire unit provides a strong mechanical bond and offers protection from the environment. These transformers are earth sealed between Primary and Secondary. They also have tappings on the input side to facilitate selection according to site voltage.

Control transformers are available in single phase and three phase transfomers available in air cooled and oil cooled type. We offer control transformers from. 5 VA- 30 KVA.
