8 Top transformers to make your power system work flawlessly

No one can live a life without electricity in these days. Electricity and energy have become crucial parts of our daily lives. All our appliances run on electricity – TVs, refrigerators, microwave ovens, home theatre systems and most importantly – our mobiles which are electrically charged. But when it comes to the matter of voltage fluctuations, our appliances may commence to malfunction. This is where Transformers can help us. They switch from one circuit to another by electromagnetic induction to reduce or increase the voltage of the electrical equipment as required.

Some of the efficient transformers –

1. Power Transformers:

A power transformer is a type of transformer used to transfer power to any part of the electrical or electronic circuit between the generator and the supply primary circuits. These transformers are used to increase and decrease voltages in distribution systems. The normal life force of these transformers is 30 years if the transformer is immersed in fluid. Power transformers can be divided into three types based on ranges. They are:

i) The range of small power transformers is from 500-7500 kVA

ii) The range of medium power transformers is from -100MVA

iii) Larger power transformers are 100MVA and above

These transformers change the voltage. It absorbs low voltage, high current circuit on one side of the transformer and high voltage low current circuit on the other side of the transformer. The power transformer is based on the Faraday induction principle. They describe the power system as the size zones of each gear connected to the system according to the ratings set by the power transformer.

2. Distribution Transformer: Distribution transformer is an electrical isolation transformer that converts high voltage electricity into acceptable low voltage levels for use in homes and business. Furnace Transformer manufacturers are fabricating distribution transformer these days.  Power is transmitted through supply transformers to reduce the high supply voltage level to the final consumption level. Almost all power supply goes through the transformer before it can be used as an end-of-life device, motor or other equipment. Distribution transformers are used in all sectors of the commercial, residential and industrial.

Distributed transformers are generally classified into several types:

  • Isolation type: liquid-immersion or dry type
  • Number of steps: single-phase or three-phase
  • Voltage level (for dry-type): low or medium

3.  Isolation Transformers: These types of transformers separate energy sources from powered equipment, thus protecting the equipment and their users. Due to their ability to reduce noise and power, they are ideal for devices that require a high quality power supply for efficient operation. The primary purpose of these transformers is to isolate the circuits against the more normal transformer operation of the voltage converter.

4. Inverter Transformers or Electronic Transformers: These are commonly used for small power converters or to obtain the required voltage. Power transformers commonly found in substations are similar to this variant, but they are used to convert large amounts of power. Not all power transformers are inverter transformers while all inverter transformers are power transformers.

5. Instrument Transformers: Also known as precision ratio transformers, they are used in conjunction with standard low-range measuring instruments to measure high values of current or voltage. As the name implies, they are converted in exact proportions to allow the attached device to measure current or voltage without running full power through the device. When the ‘current type’ of an instrument transformer measures the current at AC voltages, the ‘potential type’ measures the voltage at AC.

6. Inverter Duty Transformers: These are mainly used in solar applications and operate at the base frequency of the alternative system. These are designed for one or more output windings connected to the load of the inverter by Variable Voltage Transformers manufacturers. Due to the multiple outputs, multiple inverters are connected in parallel to the photovoltaic arrays for these transformers.

7. Servo stabilizer: It is a servo motor controlled stabilization system that delivers the correct voltage using the buck/ boost transformer booster, which captures the voltage fluctuations from the input and regulates the current output to the optimal output. For cost effectiveness OLTC Transformers manufacturers assembles servo stabilizers.

a. Dimmer (variable transformer) – It is usually circular in shape. Silicon CRGO is used for toroidal core base & copper wire with a specific turn ratio according to capacity. The primary purpose of dimming is to increase or decrease the voltage applied to the buck boost transformer. The voltage increases or decreases by only 50% of the output voltage.

b. Servomotor (synchronizing motors) – As the name implies the servomotor is the main component of the servo stabilizer. Depending on the input voltage, the motor rotates the connected arm clockwise or anti-clockwise.

c. Carbon brush – This is the moving part of the servo stabilizer that attaches to the shaft to form contacts with the matte. If the input voltage fluctuations are very frequent, this carbon brush is pre-wiped and the customer replaces it regularly. Therefore servo stabilizer manufacturers need to use the best quality carbon brush.

d. Contactor – It is the job of the contactor to reduce the output of any servo stabilizer if it exceeds the specified limit.

e. Buck Boost Transformer – Unlike the dimmer it is rectangular. EI CRGO core attached to Bob. When constructing the transformer structure, it is immersed in a varnish tank for extra protection. Insulating varnish, also known as transformer varnish, is used in all windings used in buck boost transformers to connect them before servo stabilizer rigs are ready for testing. Transformer varnish prolongs coil life and protects the transformer’s windings from environmental exposure, which can be damaged by vibrations. This varnish can be used as the best insulator for any coil of wire. Insulation transformer also includes transformer, but it is different from buck boost transformer

f. Electronic circuit – It sends signal to several parts of the servo stabilizer such as the dimmer or motor, so it acts on that signal and does their part to correct the voltage.

g. MCB–It turns the MCB servo stabilizer on / off and provides short circuit protection, while MCB is commonly used for overload protection.

8. Oil-filled transformer: This is a type of voltage conversion device that uses the oil cooling method to reduce the temperature of the transformer. Oil Immersed Transformers manufacturers are facing an enormous rush on for it. Unlike a dry type transformer, the body of the oil immersed transformer is housed in a simulated steel oil tank filled with insulation oil. When the oil transformer is operating, the heat of the coil and iron is first transferred to the insulation oil and then to the cooling medium. Depending on the size of the capacity, it can be divided into natural submersible cooling transformer and submersible forced air cooling transformer.
