Step Up Autotransformer
Step up transformer extends the voltages from 220v 11kv or above whereas step down transformer reduces the voltages from 440 220v 220 110v or 110 24v 20v 10vetc.
Step up autotransformer. Product title pyle meters pvtc120u step up and down 100 watt vol. An autotransformer can be used for step up step down and split phase output balancing purposes. Autotransformers can be used as either a step up or step down transformer. An autotransformer is an electrical transformer with only one winding the auto greek for self prefix refers to the single coil acting alone not to any kind of automatic mechanism in an autotransformer portions of the same winding act as both the primary winding and secondary winding sides of the transformer.
While the load is connected to the terminal a c as shown in the figure down below. Leverage many tools to assist you with your technical questions. Disadvantages of the autotransformer. 3 3 out of 5 stars based on 15 reviews 15 ratings current price 20 28 20.
The number of turns on the secondary of the transformer is greater than that of the primary i e t 2 t 1 thus the voltage turn ratio of the step up transformer is 1 2. 600y 480y 400y 240y 208y. The e 1 and e 2 are the voltages and t 1 and t 2 are the number of turns on the primary and secondary winding of the transformer. In conventional transformer the voltage step up or step down value is fixed while in autotransformer we can vary the output voltage as per out requirements and can smoothly increase or decrease its value as per our requirement.
1200v class autotransformer typical specification technical support. The autotransformer connection is not available with certain three phase. For performing the step up function the ac supply is connected to the variable tap point c b. Considered a step up transformer shown in the figure below.
Torque reducing gear train steps torque down while stepping speed up. Customer service faqs. Such kind of autotransformer s output voltage exceeds its input voltage vice versa for its current. The same transformer can be used as a step up or a step down transformer.
The step up step down effect of coil turn ratios in a transformer is analogous to gear tooth ratios in mechanical gear systems transforming values of speed and torque in much the same way.
