We feel extremely proud in providing the finest quality Auto Transformers to our customers. These transformers are used in power transmission & distribution systems, railways products and audio system. Precisely manufactured by making use of optimum quality materials, these transformers can be accessed from us in distinct specifications. In order to ensure their effective functionality, these Auto Transformers are further checked by our quality inspectors before dispatching.
Advantages of using Auto Transformers
When the proportion of transformation is around 2, then the size of the automatic machines is roughly around 50 per cent of the related size of a double winding transformer. On the contrary, when the ratio touches around 20, the size changes to 95 per cent in the same aspect. One key point to note is that the cost reduction of the elements is not the same. One can only gain a considerable difference in the saving factor only if the ratio of the equipment is lower than 2. This is why this auto device is smaller and cheaper.
Known for their exceptional rate of efficiency, such machinery has a less ohmic loss as compared to that of a two winding transformer, which is generally caused due to a decrease in transformer material.
Our devices come with a more reliable voltage regulation system, and the drop in voltage resistance is of a single winding is much lower.
Disadvantages of Using Auto Transformer
Due to the electrical conductivity of the primary and secondary windings, the lower voltage circuit generally gets impressed upon the higher electric force. It is of utmost importance to develop a circuit which have handle the pressure of the high powered electrical device so as to avoid system failure.
The impedance is generally reduced since the outflow rate between both the primary and secondary windings are small. This in turn becomes the major cause of short circuits under fault conditions.
The unions of both the above mentioned sides has to be absolutely identical leaving out the part when starring connections are to be merged. This brings up a number of issues in the delta section. Thanks to the neutral wired in the star attached auto transformer, one cannot join the wire from one end only. Since both regions have their own tolerance, make sure you chose the earth or isolated end wisely.
Keeping a perfect electromagnetic equilibrium is not quite easy for the winding especially when voltage fitting tappings are already supplied. One should understand that this provision enhances the frame size of the machine to a considerable degree. In the case where the range is large, the rewards received in the starting cost is lost a large extent.
