How to Upgrade Power Transformer India

Explosion of transformer causes a power outage. Manufacturers of power transformers India say that the transformers do go down, but when they start putting impact on campus operations, things get worse immediately. Besides the lost continuity of classroom instruction, the risk of security lapses, subsequent fires, fines, and lawsuits can increase the damages by four times.

How to recognize a robust transformer?

Engineers are trying harder to avail an asset that will offer cost effective and long lived service with a basic know-how of the construction, design, and materials of power transformer.

Common power transformers used at campuses are liquid filled models. Liquid filled transformers use oil or coolant for absorbing heat. Other type is dry type transformer. Dry type model is air cooled and so, there are fewer chances of leakage and fire risk.

It hardly matters if the transformer is wet or dry. Robustness is determined by the way the coils are wound around the transformer core.

The material used by manufacturers for the windings is the best quality copper, which is superior conductor to aluminium as copper provides less resistance and less heat. Moreover, aluminium corrodes that creates heat and lower the life of the transformer while posing a fire hazard.

Even the insulation has significant impact on reliability. Transformer (dry type) temperatures can reach 200 degrees C on daily basis, so neglecting insulation part can be a disastrous thing to do.

How remanufacturing (restoring) is a cost saving decision?

The idea to purchase a restored transformer or refurbished transformer is a cost saving one. There are manufacturers that sell refurbished transformer and its spares to their clients at lower price. A brand new transformer is costly and not every person can afford it. So, for such clientele, manufacturers have brought refurbished range of transformers. These are restored versions of original transformers, which are repaired by professionals using latest technology and tools.

Refurbished or restored transformers are not corroded ones. These are somehow failed at operation mode and due to unavailability of spare, users sell them at low price. These sold transformers are restored in good condition by replacing the corroded or broken spares with brand new spares.

Some stores are the answer to your emergency situations when you are unable to get a component for your transformer. You can contact restoring stores that sell refurbished transformers. They do have some spares that you can avail at really cheap prices.

Royal transformers manufacturers are suppliers of power transformers India. You can contact their experts and avail best model for your site. For details, kindly visit their official website. Don’t forget to share the reviews about this story.

Modern Transformer Spares Maintenance is not Easy

Rectifier maintenance involves master practice and thus, such transformer spares maintenance is not easy as before. Modern range of rectifiers are filled with electronic and sophisticated controls, programmable logic controllers, power conversion devices, control equipment, and cooling systems. To acquire a durable product, manufacturers make quality investment with several hours of engineering, R & D, testing and maintenance practice. In order to perform proper maintenance practice, one should have good understanding of the type of rectifier system, type of control, hazards, and safety precautions.

Rectifier control types used in the metal finishing industry are separated in following types and are available in three phase and single phase power configurations.

No control – Such type of rectifier offers limited output control and regulation. No control rectifier is used at location where a single level of voltage is needed with limited regulation.

Thyristor /SCR control

This is the most common type of control used in modern metal finishing shop, where automatic control and/ or remote operation are required. The SCR or thyristor is a solid semiconductor device that acts as a switch, conducting when they are forward biased.

Transformer manufacturing companies configure SCRs with one of two typologies for offering either primary or secondary control rectifier control.

SMPS or Switchmode Power Supplies

Switchmode technology has been used in smaller applications; however, since past 10 years, industry is able to manufacture large components to allow power ratings for the metal finishing industry. The manufacturers design these supplies in solid-state and incorporate a high speed switching regulator.

The switch is either on or off.

Since the cost of copper increased, these power supplies are cost effective due to the reduced copper content. This technology provides inherent low loss conversion from AC to DC. Transformer manufacturers are making these power supplies in ranges up to 10,000 amps in a small, efficient, and reliable package.


Chopper technology is the recent one used by manufacturers for transformer applications to convert AC to DC. This technology is used in large high current systems.

All these transformer spare parts are readily available at manufacturing unit. You can browse some manufacturers of transformer parts nearby your area and source some good reliable pieces from them. Royal transformer manufacturers are among leading companies that deal into quality spares and components. They are supplying their products to worldwide clients at best rates.

You can talk to Royal Transformer experts and get the best deal for yourself. There are many transformer spares available at their store. You can even explore their offerings online by visiting their official website.
