The Ultimate Guide to Pole Mounted Transformers

Three Phase Pole Mounted Transformers

Typically, three distinct parts make up a pole mounted three phase transformer. Electricity is highly produced using three-phase transformers. If needed, they produce massive amounts of power. They are simple to build and function as AC power converters. A three-phase transformer is an unconnected machine that transfers power from its main winding to its secondary winding. It changes the voltage from high to low or low to high. As opposed to single-phase motors, which need brushes and start capacitors to get going, three-phase induction motors can turn around in a second.

Daelim's large product line allows them to develop and manufacture a wide selection of pole mounted transformers. These reliable single phase mounted transformers and three phase pole mounted transformers come in a wide range of designs. If you are seeking pole-mounted transformer manufacturers, you may rely on Daelim, which is a reputable producer of these kinds of devices.

Pole Mounted Substation

In the case of outdoor distribution substations, pole mounted substations is a type of substation that is often constructed on poles.

This substation design is the cheapest, smallest, and easiest to install. There is no requirement for a structure to house this substation. 

This pole-mounted substation supplies most of the electricity for our home.

Moreover, pole mounted transformers are highly engineered to last, despite being primarily stationed in harsh environments. 

Their tanks are highly constructed with the prevention of rust and mildew in mind.

It can withstand extreme corrosive environments due to 3CR12 steel components.

Oftentimes, you can see models such as single phase pole mounted transformers.

Yet, a three phase pole mounted transformer can only have so many bushings due to the vector designs.

How Do Pole-Mounted Transformers Work?

Pole mounted transformers are on concrete poles so that the electricity they generate is equally transmitted perpendicular to the electrical lines.

To make the high power more manageable, these transformers step it down to 400V. 

In most cases, engineers favor these pole mounted transformers due to their lightweight and minimal aesthetics. 

Larger units require two poles, however, smaller ones that are less than 5 meters in height may be generally fixed securely on buildings that only require a single pole.

As a result, both humans and animals are generally protected from harm, and acts of damage are less likely to take place.

How Does A Pole Mounted Transformer Operate?

When a transformer is functioning correctly, current flows into the inductor coil, which is often linked to a metal. 

This coil can successfully focus the electrical current from the other coil. 

Because of this, it flows in its own direction and produces a fluctuating electric current.

Pole mounted transformer insulators are generally hardwired into the power grid at the station. To connect the devices, the go switch must be mainly switched on.

Because of potential sparking problems, certain pole mounted transformers do not have an ON button. 

Power Plant Distribution

At a power plant, voltage is generally increased to several hundred thousand volts. 

The voltage is then reduced to a few thousand volts somewhere near residential houses. These substations seem like fenced-in lots filled with enormous transformers and insulators. 

Power is then transmitted to your neighborhood through poles or conduits. There, it gets reduced to 120/240 V and is mainly wired into your home. 

Electricians usually refer to them as "pole pigs." Electricity may be generally distributed from a single pole pig to several dwellings.

In What Range Of Voltage Does A Pole-Mounted Transformer Operate?

High voltage is often supplied to pole mounted transformers by substations in the direct vicinity.

Pole mounted transformers are often known as distribution transformers. 

Such transformers often receive input voltages of up to 13 kilovolts (kV) single phase relative to ground.

The power that runs through these transformers comes in three separate phases. 

Typically, this is between 5kv (5000v) and 35kv (35kv) (35,000v). For 60 hertz systems, 11kv and 15kv are the standard in most power networks.

How Many Residences May Be Serviced By A Single Pole-Mounted Transformer?

As many as the power supply can support.

In some cases, a single-family home will be the limit of a 10 or 15 kVA transformer's output. 

Whether a home contains an electric heater, water heater, clothes dryer, or stove, the load might be anything from a few hundred to more than twelve thousand watts. 

If fifty homes use gas appliances throughout (oven, water heater, clothes dryer, and heater), a single enormous transformer might power all of them.

Pole Mounted Transformer Substation Capacity

Voltage Scale

The voltage rating of the pole-mounted transformer substation is 11 kilovolts / 400 volts. Single-phase line voltage is 230 voltage and three phase line voltage is 400 voltage.

Current Capacity

The power output of the pole-mounted substation shifts in response to changes in demand. By correctly configuring the current balancing mechanism, the transformer may function at peak efficiency.

Power Capacity

The pole-mounted transformer substation has a 250 kVA capacity.

Transformer Connection

Pole-mounted transformer substation is usually connected to the electricity grid using a delta-star configuration.

Why Are Pole-Mounted Transformers Grounded?

To ensure that electrical current has a safe path in the event of a breakdown or ground fault, a pole mounted transformer must be always grounded. 

As you can see, to guard against electrical shock, lessen electrical noise, and shield electronics from harm, grounding is essential.

In addition to guaranteeing that the voltage levels in an electrical system are safe, a ground connection also serves as a reference point for the system.

Additional Points:

1. It is preferable to maintain the lowest feasible voltages in the system relative to the ground. One of the most effective methods of doing so is to ground the secondary neutral winding.
2. Second, it's preferable if any potential short to the transformer's exterior lasted as little time as feasible.
3. By connecting the casing to the ground, the transformer's over-current protection is mainly activated and the potential threat is basically removed.

Keep in mind

Any transformer that isn't grounded runs the risk of accumulating an electrical charge that might cause serious harm to nearby equipment or people. 

This can also potentially break through protective coverings, causing irreparable damage to the transformer, and exposing the environment to its high voltages. 

When struck by lightning, only the ground can conduct the voltage to the ground.

Assuming we have a 12KV overhead line. 

At first, the breaker is mainly connected to the 12KV cables. In most cases, three fuses are not visible because of the constraints of a single line. 

The fuse's terminal serves as an input for the isolator. The output of the isolator is then connected to the transformer's input terminal. Then the one that connects to the transformer's output is the oil circuit breaker.

The oil circuit breaker's output is also delivered to residential homes. The incoming power source is then linked to the power supply.

Oftentimes, the total voltage for three-phase consumers is 400V. Single-phase clients receive 230 volts (V) (two phases plus a neutral).

By dividing the load evenly across its single-phase consumers, the transformer can perform at its peak efficiency.

Pole Mounted Transformer Construction

The most common location for pole mounted transformers is at the very top of the pole or overhead.

The incoming current is then sent to the transformer through the gang isolator and HT fuses. 

In this case, a mechanical gang isolator switch with three poles is highly applied. When you pull the handle at the base of the isolator, it will shut off the transformer.

In the event of an issue on the low voltage side of the transformer, an oil circuit breaker will trip and cut power to the load or consumer on the high voltage side.

The transformer's high voltage isolator and low voltage circuit breaker must be then disabled before any servicing or repairs.

Due to the lower capacity equipment and construction, the pole mounted substation has far lower installation and maintenance costs than conventional substations.
