A booster transformer is a type of transformer designed to raise the voltage level on an electrical power line, compensating for any drops in voltage caused by long distance transmission.
Typically, this method requires only the line voltage or supply voltage to be altered, which may or may not affect other terminals in the plant. Buck-boost transformers offer the additional advantage of reducing voltage sags that could otherwise negatively impact equipment performance or cause premature failure.
A booster transformer is a type of transformer used for controlling voltage on an electrical line. It typically sits at the end of the line to boost its voltage up to the desired level.
Electric railway traction systems use a booster transformer to regulate the return current from catenary wire and earth connected rails. This helps eliminate stray currents and disturbances.
Return current is brought from the catenary wire of a locomotive and used by motors before returning it to rails connected to ground through a return conductor. Without an external booster transformer, however, this returning current may flow around unintended or hazardous places like metallic pipe lines and bridges, communication cables, etc.
Due to a low ampere turn ratio (BT) of 1:1, returning current cannot flow through the return conductor. With an added booster transformer, however, the returning current is forced into another path towards the return conductor and interference effects are minimized.
What is the use of booster transformer?
Railway booster transformers are used to eliminate stray current that disrupts communication systems and damages electronic devices on trains passing through them. This stray current arises due to leakage of returning current from rails back to ground.
Booster transformers typically feature a unity turn ratio and their primary winding is connected in series with the contact wire, while their secondary winding is linked to the return feeder. When current flows through the contact wire, it induces voltage in the secondary winding which restricts it to only passing through the return feeder.
This method of using booster transformer has several drawbacks, the primary being that it places feeding posts in series with the traction circuit, increasing its impedance and leading to poor voltage regulation in locomotives. To improve voltage regulation, either move the feeding posts closer together or add a capacitor of suitable value in series with the traction circuit.
Which transformer is used as booster transformer?
The booster transformer is the key component in compensating for voltage losses when power is transmitted over long distance. For instance, a power line running from one end of the country to the other must maintain constant voltage levels throughout its journey from source plant to destination station.

What is A boost current transformer?
A boost current transformer, also referred to as a buck-boost transformer, is an electronic device used for adjusting the voltage applied to alternating current equipment. It’s commonly found in uninterruptible power supply (UPS) units, tanning beds, lighting systems and other similar applications.
Buck-boost transformers differ from standard transformers in that they alter the input voltage to a value that may differ significantly from its output. Generally, these modifications to supply line voltage are negligible–usually less than +/-30 percent.
Buck-boost transformers are typically compact in size and designed for single-phase voltage rectification. Some models also offer low voltage rectification capabilities, making them suitable for outdoor areas, lighting systems or combustible facilities.
Businesses or projects that often utilize buck-boost transformers include MRO, construction, mining, remote facilities, military camp sites, emergency medical services, shipyards, aerospace facilities and plant maintenance. Capacity ranges from 10 KVA to 150 KVA.
What is the difference between booster transformer
Booster transformers are used to compensate for voltage drops caused by losses in the power line. There are various types of booster transformers.
The main advantage of a booster transformer system is that it eliminates stray current flow, thus reducing interference effects. Unfortunately, it also has some drawbacks such as increasing impedance on the traction circuit and lacking isolation.
This method involves inserting the primary winding of a booster transformer in series with the traction wire, while its secondary winding is connected from the regulating transformer’s primary (see Figure-1). This causes voltage in the secondary of the booster transformer which then causes return current only through its rails.
Booster transformers are frequently employed in railway traction systems to improve voltage regulation of a train by cutting down on stray current. These transformers are usually situated close to the traction circuit.
What is the disadvantage of booster transformer?
Booster transformers are employed to boost the voltage of a power line and can also be utilized for voltage regulation.
Furthermore, transformers can be utilized to isolate equipment from Earth connection – an invaluable benefit for safety purposes.
Another advantage of this type of transformer is that it can measure high currents or current in high voltage lines for metering without interrupting the circuit or making contact with its terminals.
The disadvantage of this transformer is its lack of primary to secondary winding isolation, like a traditional double wound transformer. If there’s an electrical short in the autotransformer, much larger currents could flow through its primary winding than would occur with an equivalent double wound transformer – potentially damaging it in the process.
The major disadvantage of this type of booster is its inability to withstand voltage surges that occur along transmission networks. This becomes even more critical if the series winding is connected to system interconnectors with ratings in excess of hundreds of MVA.
What are the 3 types of transformers?
Transformers are electronic devices that take in high voltage electricity and reduce it into smaller amounts by wrapping the output wire around a core with many coils encircled.
When electric current passes through a primary coil, it produces an oscillating magnetic flux which, in turn, induces an electromagnetic force (emf) on the secondary coil. This phenomenon is explained by Faraday’s law of electromagnetic induction.
On the market, there are various types of transformers. They are usually classified based on their purpose or usage.
Booster Transformer: This type of transformer is one of the most commonly used. It increases power to a power line and improves its performance, acting as either a phase-shifter, quadrature booster or regulating transformer.
Phase-shifting transformer, also known as a phase angle regulating transformer (PAR) or quadrature booster, is an electrical device that creates a phase shift between primary and secondary sides of a circuit. It’s typically employed to enhance power transfer efficiency in AC networks.

What is the Difference Between Buck and Boost Transformer?
A buck or boost transformer is an autotransformer that adjusts line-in voltage by a small percentage. These units are commonly employed in both single phase and three phase electrical distribution networks.
Buck or boost transformers serve the primary purpose of providing a means of adjusting the line voltage for devices to meet their power demands. This essential function can be affected by factors such as line losses, equipment demand on the system, and in extreme cases voltage sags on the line.
A buck or boost transformer typically utilizes an additive-polarity connection to increase circuit voltage, while a subtractive-polarity connection decreases it. When this technique is employed to boost an inadequately high circuit voltage, the circuit is known as a boost configuration since the secondary winding voltage is added to the line or supply voltage in order to “boost” its primary winding level.
Buck or boost transformer secondary wires are typically connected in parallel, allowing for a wide range of voltage and KVA outputs depending on how they’re wired. This flexibility comes from being able to connect primary and secondary windings through different methods such as taps on each coil. This adaptability makes buck or boost transformers ideal for use in many different applications due to their versatility.
What Are the 2 Types of Transformers?
Transformers play an essential role in nearly all power distribution system applications. Examples include commercial buildings, schools, hospitals, water/wastewater treatment plants, industrial processes such as oil & gas and data centers; they’re ubiquitous everywhere!
A typical transformer consists of several secondary windings or coils of insulated wire conductor wrapped around a laminated steel core. Voltage is applied to one coil, called the primary, magnetizing its iron core and inducing a voltage in another one known as the secondary or output coil. The difference in voltage (or voltage ratio) between these two coils depends on their turn ratios.
Transformers serve a primary purpose by converting supply voltage from high to low. They are essential elements in electrical power systems.
Transformers come in two primary varieties: step up and step down. On step up transformers, the turns on the primary side are greater than those on the secondary side.
Step up transformers are commonly employed to convert high grid voltage into the domestic voltage required at the consumer end. They offer an efficient solution for distributing electricity over low voltage networks and can even carry power from industrial plants directly to end consumers.
Step down transformers are also employed in industrial plants to convert high grid voltage into low voltage for delivering electricity at lower voltages. They offer a reliable option for delivering power at these lower levels.
