Isolation transformers are used to transfer electrical power from a source of alternating current power to a device, where the powered device is isolated from the power source for safety measures. They provide galvanic isolation, which is the principle of isolating different sections of electrical systems to prevent current flow. Here, there is no direct conduction path but, the energy is still exchanged between sections by capacitance, induction or electromagnetic waves. However, these transformers block the transmission of the DC component in signals from one circuit to another, while letting the AC components to pass.
We all know what the famous ‘W’s are – Who? What? Why? When? Where? Which? Do you know that most of these Ws can be asked in the case of transformers too? Here are the questions that almost every individual dealing with transformers would want to have the answers to.
With the fuel costs rising and power cut offs becoming more widespread throughout the country, the focus has shifted majorly towards power generation and distribution. It has also become highly important to conserve energy and invest in energy efficient products of all types. This is the reason why power transformers have become a very important part of everyday life today because of its constant energy throughout the day. If even a single unit goes off for a short time period, multiple households and commercial spaces are thrown into darkness, which results in a considerable economic loss. However, distribution transformers that are more than 30 years old can waste between 60 to 80 billion kWh every year! When such transformers are replaced with newer and better designed transformers, they can yield annual energy savings up to 100 crores of rupees!
Every country has its own varying alternating current. Generally, most of the world operates on 220-240 VAC (Volts Alternating Current). North America is one country that operates on 110-120 VAC. When you travel from one country to another, if you are to experience a voltage fluctuation, you need to be well prepared to convert the voltage to match your appliance’s voltage requirement. If you fail to do so, you could severely damage your appliances.
Transformers are electrical instruments that are used to transfer current from one source to another. They are available in different kinds like electric, current, isolation, toroidal, audio, high voltage and many more. All of these are manufactured in different ways and to satisfy different demands of customers, may it be industries or for general usage. Miracle Electronics is a leading transformer manufacturer in India who manufactures many different types of transformers to be sold at reasonable and affordable prices, without compromising on quality of materials used and the labour involved. Here is a list of some of the transformers popularly used.
Automatic voltage stabilizers automatically correct the voltage at regular intervals, resulting in a consistent voltage being supplied to motors. This consistent voltage helps in an efficient operation of electrical equipment, preventing any kind of damage caused to them due to voltage fluctuations. This increases the efficiency and decreases the maintenance costs involved for all your equipment. Ultimately this will result in zero production loss and will improve the efficiency of your plant.
Isolation transformers are those that provide galvanic Isolation between two or more windings that provides protection against spikes and noise. Transformers used in medical electronics should be able to meet strict safety standards as per the BS EN 60601 or any other relative standards like CSA c22.2 No. 125, VDE 0551 or IEC 601.1. There are many different applications in the medical industry that require Isolation transformers and each one of them requires a different design.
Can you imagine your life without electricity? Or, can you imagine even a day without electricity? Obviously not! Electricity is one of the most important elements of our daily life. We have so many appliances, electronics and gadgets today that are the most precious to us. And, we can obviously not use all of these technologies if we have no electric current. But with electricity, there are so many issues of power cuts across the country. Many cities in India face sudden power failures and voltage problems, and continuous issues like these results in the breakdown of appliances within our home. So, is there a solution to this? There is only one way out to set these problems right – and that is by using a transformer.
Unlike liquid fill transformers that require oil or liquid to cool, dry type transformers use only high temperature insulation systems that are environmentally safe. Dry type transformers are static solid state devices with no moving parts, which require minimum maintenance and provide a long reliable trouble-free life. Because they are completely hazard-free, these transformers can be easily installed in hospitals, schools, factories, chemical plants and buildings where fire safety is a great concern. They can be easily installed indoors as well as outdoors only confirming that there is enough ventilation. However, one drawback with these transformers is that they are easily affected by dirt, dust, moisture and corrosion because the windings are exposed to air. Therefore, these transformers need to be periodically cleaned to prevent dust and other contaminants to build up over time.
How does electricity travel from the generator into the homes of people residing in the city? Have you ever thought about it? Electricity is required to travel long distances through wires that are exposed to all sorts of climates all-round the year. Electricity also produces a lot of heat, much of which is wasted during the entire process. This is why when it starts its journey from the generator; it should be changed into high voltage by Toroidal power transformers. More than 50 thousand volts of high voltage electricity travels in every wire across the world. When this electricity reaches the city, it gets deviated into low voltage transformers.
