Wed, 17 Oct 2012 11:01:26 +0530

A Voltage Transformer is a device that gauges and protects the safety levels in high and low-voltage circuits. A very small amount of load to a supply that is being measured is allowed by them for the creation of an exact Voltage ratio for stepping the voltage up or down with accuracy. A Voltage Transformer is used in devices like radios, TVs and computers. Voltage Transformers are extremely helpful in places where the electricity supply is not regular. Voltage Transformers help in regulating the flow of the electricity into these gadgets by using the step-up or step-down function and prevent the damage to the circuits of these gadgets. In order to install the ideal Voltage Transformer for a house or an office, it is necessary to note the wattage required by the items. Power strips are usually used to connect many gadgets to the items, so that multiple items can run through one large Voltage Transformer. Voltage Transformers are generally used with 3-pin appliances, that is, ones that are grounded. Voltage Transformers are of great advantage in several ways. The purpose that High Voltage Transformers serve is different from Low Voltage Transformers, but both are equally useful in different categories. High Voltage Transformers are used in CRT Displays, medical equipment and amplifiers. Laminated Transformers are used in lighting, motorized gates, controls for alarms, air-conditioning and vending machines. They are also used in the making of Isolation Transformers, telephone networks, measurement instruments, medical equipment, sound reproduction equipment. Low-Voltage Transformers are extremely efficient and so, very helpful to its users. A Low Voltage Transformer is also known as the Magnetic Low Voltage Transformer as it transfers electrical energy from one circuit to another, using magnetic coupling. A major advantage of Low Voltage Transformer is that with this device, the chances of electric shocks are reduced to minimum. This Voltage Transformer is used in domestic appliances.

All That You Should Know About Electrical Transformer

Mon, 23 Sep 2013 11:23:19 +0530

Electrical Transformer is a technologically advanced mechanism that transforms current voltage from particular circuit to other electric circuit via electromagnetic induction. It increases or decreases the voltage that comes from the substation. By and large, the Electrical Transformers, also known as Power Transformers, are used to convey current from power plants to commercial as well as residential places. The Categorization: On the whole, Electrical or Power Transformer is a liquid filled unit that can be classified into 3 size categories, that is, small power (below 10 MVA), medium power (from 10 to 50 MVA), and large power (above 50 MVA). Though this categorization is not recognized by CSA, ANSI or IEEE, however, most of the times, is referred to by the consultants and manufacturers. Service Life Of Electrical Transformer: A typical Electrical Transformer’s life expectancy can be determined by a number of factors, the primary of which being the excellence of its insulation system after certain period of time. Elaborating further, the oil used in Electrical Transformer is mostly subject to moisture and in the presence of even very less amount of water the transformer’s insulating value gets acutely reduced. Apart from this, the oil’s performance as a cooling medium as well as insulating quality can be reduced by oxidization too. It is, hence, very crucial that the structure and the design of Electrical Transformer is such that it slows down the contact of insulation system to the external environment that is full of both oxygen and moisture. Nevertheless, any typical Power Transformer comes with a substantial life cycle of around 30 years and it not at all means that the transformer cannot be used beyond this duration. Consideration: Undoubtedly, Electrical Transformers are the heart of every electrical distribution and transmission system. In order to ensure that the Electrical Transformer operates with maximum security, it is prudent to check that it works as per the specific overload capacity and limit load. Also, the Electrical Transformer must be checked on a regular basis so as to avoid unexpected power-related incidents. Buyers can make contact with Urja Techniques (India) Pvt.

A Brief Overview of Electric Furnace Transformer

Tue, 18 Feb 2014 12:26:07 +0530

Transformers are designed for transferring electricity from power plants to several areas in voltages paced down according to the requirement. The function of the Electric Furnace Transformer is to maintain a balance in the distribution of electricity in circuits, machines and other equipment that require power for functioning. Talking specifically about the Furnace Transformers, they are basically used to reduce the voltage fluctuations that can lead to the breaking down of the electrical equipment. Their load cycles vary depending on the metallurgical requirements and size. There are two types of Electric Arc Furnaces – direct furnaces and indirect furnaces. The difference between the two of them is direct arc furnaces have three electrodes while the indirect ones have only one. Purpose Of Electric Furnace Transformers At times, power supply is at very high voltages that are not suitable for the furnace arcs. Hence, the voltage must be converted according to their requirement lowering it down. Electric Furnace Transformers take high voltage current transforming it into low voltage power that is suitable for the electric arc furnaces. Hence, the transformers act as energy converters that take down the power from high to low voltage. Some of the features of Electric Furnace Transformers are listed down: Features of Electric Furnace Transformers Many of the steel making arc furnaces and ferroalloy smelting furnaces require frequent load interruptions in a day. The furnaces with large capacity receive power from high power systems which is economical for them. Hence, the transforms are designed to offer minimum power loss as they regulate the flow of electricity. The transformers compensate for the flickers occurring in the steel making arc furnaces. Flicker in them occur due to the fluctuations in the power system caused by the changes in arc during an operation. This makes them improve the production efficiency and even improving the product quality. They are equipped with multi-parallel twin coil disc windings that make them suitable for low voltage and high current applications. They allow for uniform distribution of current in the parallel conductors reducing the load loss and preventing the overheating. Based in Mumbai, Urja Techniques (India) Pvt.

Importance Of Power Transformers

Mon, 21 Apr 2014 15:55:06 +0530

Electricity has become an integral part of our day to day life; as a matter of fact, it is hard to imagine our life without electricity. Today, we have become so dependent on electricity that even a minute disturbance in the form of voltage fluctuation can disrupt our daily routine to quite an extent. When electricity is being transferred over long distances, high voltage is required to get the job done efficiently. But once this high voltage electric current reaches the receiving end, it needs to be reduced to the levels required by the end user. This function is performed by the power transformer in a cheap and efficient manner. What Is A Power Transformer? A Power Transformer can be described as an electrical device that is designed to transfer alternating current from one electric circuit to another through electromagnetic induction. As mentioned earlier, the main purpose of a Power Transformer is to reduce or increase the voltage as per the requirement. These transformers enjoy a long and trouble free life since they do not make use of any moving part and stay in a static state under normal working conditions. The main function of a power transformer is to make use of the electric current and prevent damage to the internal circuitry of any electrical equipment. In addition to this, the importance of a Power Transformer is as follow: Low Operating Temperature: When we talk about transformers, operating temperatures play an important role. Power Transformers are built to cater to temperature rise of 40-50 Degree C. When a power transformer operates at half its load, the temperature rise is usually ¼ of the temperature rise at full power. Low Magnetic Fields: Power Transformers are known to emit extremely low radiated electro-magnetic fields. This makes them perfect for use in electronic equipment such as low level amplifier, medical equipment. Voltage Regulation: The voltage drop under load of a Power Transformer is much lower when compared to other types of transformer. Urja Techniques (India) Pvt.
