Different Types of Power Transformers

Power transformers can be described by the word “Power Transformers”. Power transformers are used to alert power that is being transmitted to a higher voltage. They can transmit power at very high voltages. Through their resistance, transformers can reduce power loss. The received power will be carried within a specified range. This ensures that the power is used in accordance with local requirements. It typically includes Buck Boost Transformers. These are used for fine tuning low voltage applications. Step Up transformers are used to increase the low voltage constant condition. If the voltage is 108 V, it will raise it up to 120 V. Step Down transformers, unlike Step Up, will help to reduce voltage from high-voltage conditions. There are many different types and uses for transformers. Here are some examples of how different types can be used. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.

Resonant transformers

Resonant transformers can be described as a leakage transformer. It uses the leakage-inductance of its secondary windsings in combination with external capacitors to form one or several resonant circuits. Tesla coils can produce very high voltages. They are capable of supplying much more current that electrostatic high-voltage machines.

Instrument transformers

It serves the main purpose to measure voltage and current in electrical energy systems. It is used for power system protection, control, and control. It can be used to reduce voltages or currents that are too large to be suitable for an instrument.


Autotransformers cost less than a standard double-winding transformer, and are also smaller and lighter. An autotransformer doesn’t provide electrical isolation. Autotransformers allow you to switch between voltages in both the 110-117-120 volt range or the 220-230-244 volt range. The autotransformers can produce 110 or 120V with a 230V input. This allows equipment in a 100 and 120V range to be used within a 230V area.

Leakage transformers

A leakage Transformer, also known as strayfield transformer, has a significantly higher leakage current than other transformers. This is sometimes increased by a magnetic bypass, thrust or magnetic bypass in its core, which can then be adjusted with a set screws. It is the primary purpose for arc welding, high voltage discharge lamps, and other applications. It serves two purposes: as a voltage regulator and as a magnetic balance transformer.

Polyphase transformers

Polyphase Transformers are used to provide three-phase power. These Polyphase transformers use three-phase supplies. Their magnetic circuits are joined to the core, which holds a three phase flow of flux. There are many options for winding configurations, each with its own attributes and phase changes. Grounding and suppression of harmonic currents are the primary purposes.

Audio transformers

Audio transformers were specifically made for audio circuits. They are useful for obstructing radio frequency interference (or the DC component) of an audio signal. They were initially designed to connect several telephone systems while keeping their power supplies isolated. Today, they are used to interconnect professional audio systems and system components.
