What is a step up transformer?
Step-up transformer has more number of turns in the secondary winding and less in the primary such that voltage is more in the secondary when compared to primary. The number of turns in both the windings is decided by the application rating requirement.
Open and Dry type
Primary (low voltage) winding with less no. of turns
Secondary (high voltage) winding with more no. of turns
Power range: 7.5KVA-150KVA
Voltage range: Any input voltage (eg. 12VAC, 24VAC, 36VAC, 48VAC, 110VAC), any output voltage (eg. 110VAC, 220VAC, 230VAC, 380VAC, 400VAC)
Frequency range: 50Hz, 60Hz, 50/60Hz or 400Hz
a. Step-up transformer is used in transmission lines for transforming the high voltage produced by the alternator.
b. The output current of the step up transformer is less, and hence it is used for reducing the power loss.
c. The step-up transformer is also used for starting the electrical motor, in the microwave oven, X-ray machines etc.
Open and enclosed transformers with different IP ratings and mounting are available.
