subject: Tips To Purchase Voltage Transformers [print this page] In today's times, one can hardly imagine a day without electricity. This is the prime reason which has escalated voltage transformers into prominence. Now the question that arises is what is it that makes voltage transformers so useful. Well, the answer is not that difficult to find. Today, voltage transformers are being utilized for metering and protection in high-voltage circuits. They are also extremely handy in cutting of any, even negligible, load to supply if it goes beyond permissible limits. It thus maintains a perfect voltage ratio which keeps tight vigil on voltage and does not allow it to escalate.
Voltage transformers, it must be understood, are used with grounded, three pin appliances. They can be used with electric as well as electronic appliances. Voltage transformers can also be used for longer durations and at higher watts.
It must be noted here that voltage transformers can be classified into two categories. One is low voltage transformers or step down while other is high voltage transformers or step up. The purpose of low voltage transformer is to keep the voltage level on the lower side. For instance, bring it from 200V to 100V. High voltage transformer on the other hand, lifts the voltage level, raising it from 100V to 200V.
If you want to purchase voltage transformers then it is advised that you keep below-mentioned points in mind.
It is imperative to properly analyze whether your appliance actually needs any transformer at all. To ensure this, see the voltage rating on the equipment. If it reads somewhere around 110 to 240V then it is a dual voltage appliance. Such appliances can be used in a 220V without any transformer. On the contrary if the voltage rating reads 110 or 120V then it means that the product is single volt and would require a low voltage transformer in 220V.
Once it is established that a voltage transformer is required, the next step should be to ensure that an appropriate product is purchased for the appliance. However, buyers are advised to purchase voltage transformers only after considering wattage rating of their appliances. Normally, one should go for a voltage transformer that is at least 25% higher than the product's wattage rating.
It is also advised to have appropriate plug adapter before purchasing the transformer.
Remember, one should always purchase voltage transformers from a reputed shop only.
Adhering to these above mentioned points would ensure that your purchased voltage transformers suits to your requirement.
