What are Pad-mounted Transformers?

So, what are Pad-mounted Transformers? Pad-mounted transformers are basically a type of transformer or an electrical device that sits on a pad made of concrete, (the material of the pad could also vary).

This type of transformer also has a different appearance compared to other types of transformers that you normally see in electrical plants or establishments. Furthermore, Cooper Pad-mounted Transformers have their unique functions, mechanisms, design, and diagram as well.

In this section, you will go through the Pad-mounted Transformer Specifications, which is essential to fully get to know what this type of transformer is capable, and if it fits your needs.

Pad-mounted Transformer Structure

In terms of the structure of Cooper Pad-mounted Transformers, you would normally see them as an ordinary metal box that is enclosed in a metal fence or borders to prevent outside elements like pedestrians and animals from interfering with its operation.

The Inside a Pad-mounted Transformer is also filled with oil on almost a regular basis since this is how these electrical devices work or operate at best. Moreover, its location to where it is supposed to be placed is for outdoors only.

Cooper Pad-mounted Transformers are also like other types of transformers that have their own core and coils as well. The core and coils of Cooper Pad-mounted Transformers are normally enclosed in a steel oil-filled tank, which you will get to know more as we go through its specifications deeper in the article.
The tank has a terminal for the transformer to be accessible in an adjacent lockable wiring cabinet setting. Furthermore, the wiring cabinet consists of two wiring compartments, which are the high and low voltage ones.

Pad-mounted Transformer Diagram

Before discussing the Pad-mounted Transformer Diagram, if you do not know what a diagram for transformers is, it is basically referred to this way. Normally, transformers have two coils that are electrically isolated, and they are operated on Faraday’s principle of the law of mutual induction.

This means that an Electromotive Force or E.M.F is induced to the secondary coil of the transformers, and this is caused by the magnetic flux that is created from the voltages and currents that are flowing or passing in the primary coil winding, and this is what the Pad-mounted Transformer Diagram follows.

Pad-mounted Transformer Parts

In this part of the article, you will be provided with information regarding the numerous parts of the Cooper Pad-mounted Transformer. Moreover, this section still focuses on the Pad-mounted Transformer Specifications.

DAELIM professionally engineered their Cooper Pad-mounted Transformers to perform at optimum levels, which means that there are additional parts in the transformers that they manufactured that other Pad-mounted transformers do not have.

For instance, DAELIM’s Cooper Pad-mounted Transformers combines the function of a conventional distribution transformer with a Vacuum Fault Interrupter or V.F.I. The combination or the mix of these gives the Cooper Pad-mounted Transformer the ability to transform voltages.

Furthermore, the transformer overcurrent protection provides a cost-effective application and cost-effective package.

Pad-mounted V.F.I transformers are responsible for protecting the transformer, and this provides the proper coordination with the upstream protective devices as well. In the occurrence that a fault or overload happens, the V.F.I breaker will trigger, and the result of this will isolate the transformer.

Three-phase V.F.I breakers usually consist of an independent single-phase initiation. However, the three-phase of these will be mechanically gang-tripped.

Connection Mode of Working Winding of Three-phase Transformer

A single trip to the signal that is on any phase will cause the three phases to open. This feature is specifically designed to eliminate single-phasing that can happen to one of the phases in the three phases.

Furthermore, this feature enables the V.F.I breaker to be utilized as a load break switch in a three-phase setting. The characteristics of the V.F.I breaker is what makes the breaker unlock faster and easier,

The sealed visible break window and switch is an optional feature that can be installed to the transformer, and the main purpose of this is to provide visible break contact. Moreover, this promotes an enhanced safety mechanism, and transparency for the load break switch if it is in an open or closed position.

Below are more details of what is inside a Pad-mounted Transformer.

The plates are primarily clamped in place with the help of presses and bolts that is used to form the solid core and coil assembly.


Transformer insulation
Transformer insulation

When it comes to the Cooper Pad-mounted Transformer’s tank, it is basically designed to withstand high-strength operations, but it is conveniently easy to handle. Moreover, the installation will not be an issue, and as well as maintenance since it has little to almost no maintenance at all.

Doing your part in maintaining your transformer’s tank will make it last for a very long time. Monitoring it every once in a while is a good practice that is highly recommended.

In terms of its process of creation, they are specifically welded with precision cuts, oiled steel, pickling, etc.

These are sealed to protect the insulating fluid as well, and this includes other internal components. Transformer tanks are also pressure-tested, which means they can withstand 7 PSIG without having any problems or complications against distortion and rupture.

Tank Finish

Tank finish refers to the multi-stage finishing process, and like the core and coil assemblies, this also exceeds the requirements of the I.E.E.E std C57. 12.28 2014 standards. This eight-stage and pre-treatment procedure ensures optimum coating and adhesion that makes it resistant to corrosion.

When it comes to the tank’s surfaces non-metallic iron phosphate coating is essential. The paint method is composed of two distinct layers of pain. The E-coat or first epoxy primer is responsible for providing a barrier that is against moisture, salt, and corrosives.

Two-component urethanes final coat seals and ultraviolet are the final touches to this process.

Vacuum processing

Vacuum processing is primarily used to fill up transformers with their insulating liquid or cooling medium, and vacuum processing also has a major role in energizing the secondary windings.

The coils that are heated and driven out of moistures ensure optimum penetration of the mineral oil to the coil insulation system.

Cooling Medium

DAELIM’s Cooper Pad-mounted Transformers utilize mineral oil or commonly known as transformer oil for their cooling medium, which is an effective cooling medium compared to pressurized air that is used on dry-type transformers.

However, it is worth noting that mineral oil or transformer oil does have its pros and cons. For instance, DAELIM Dry-type Transformers have less maintenance since they are static devices that do not need an oil change, whereas DAELIM Oil-filled Transformers require regular maintenance due to their oil usage.
