Transformers And Its Five Types

Transformers, are one of the most useful inventions in the realm of electrical engineering. They are used in various electrical equipment applications such as water pumps, food service and electronics, pool and spa, HVAC, and more. Although there are variants available, but the end result of all the transformers is to transform the electrical power from one type to another. Trutech Products is a prominent Transformer Manufacturers in India, offering a wide array of transformers in different specifications as demanded by the clients.

Working of Transformers

It is as we all know a passive electrical device, majorly designed to convert ac voltage to another, making use of magnetic induction. To match the requirement of the utility's incoming supply voltage, the transformers can either 'step up' or 'step down' the voltage. To meet the requirement of the application areas, there are transformers available in variants based on voltage levels, winding arrangements, and application areas.

The Five Types of Transformers:

• Isolation Transformer

The isolation transformers are widely used for their property of preventing shock hazards. In order to isolate the circuit from the source supply, the transformer has primary as well as the secondary winding. In case of an electricity circuit breakdown, the transformer provides aid against the power rush. These transformers work well in areas such as telecommunication, remote control equipment, and the medical industry.

• Auto Transformer

This type of transformer has one type of winding that is shared between both primary as well as secondary circuits. Substantial savings is also assured as there is no isolation when the transformer is used to achieve a little higher or lower the original input voltage. The transformer is therefore considered ideal for low voltage applications like induction motor starters.

• Class II Transformer

The Class II Transformers are ideally designed to meet the requirements of the HVAC/R control systems that require supply to Class II circuits. The transformers are designed to offer 75 VA (volt-ampere) to 100 VA (volt-ampere), as required by the application area. In the construction of the transformer, you will also find that these are inherently or non-inherently limited. This means the maximum output current by the transformer is limited by a breaker, fuse, or intrinsic coil impedance. There are Transformers manufacturers in India, who are acclaimed for offering a range that can deliver up to 150 VA (volt-ampere) or even 200 VA (volt-ampere).

• General Purpose Transformer

Reconciling with the name, this transformer type is used for almost every application requiring low voltage, such as general lighting. Primary as well as secondary voltage ratings up to 600 VAC (volts alternating current). Although there is an internal fusing option available, hence no extra fusing option is required.

• Control Transformer

Similar to the isolation transformer, the control transformer is designed to deliver rated output voltage at full VA (volt-ampere). As there is a decrease in the load, the output voltage simultaneously goes up. On the other hand, if there is an increase in the load, the output voltage with eventually decrease. The main purpose of these transformers is to control or regulate the voltage in the common application.
