Power Transformers describes the purpose of Power transformers. It transmits power to alarm the power being transmitted at a high level of voltage. The resistance of transformers helps to minimize power loss. It can deliver the received power within an exact range of power and will ensure that the power used is in line with the local needs. It usually comprises Buck Boost Transformers. This is used to tune low voltage applications. Step Up transformers increase the constant low-voltage condition (i.e. If it’s 108 volts it will increase the voltage to 120. Step Down transformers will not reduce the voltage at high voltage. There are many kinds of transformers. Each type is useful for different purposes. Here are some uses of various types of transformers. 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 Transformer is a type leakage transformer. To form a resonant circuit, it uses the leakage potential of its secondary windings and external capacitors. The Tesla coil is capable to produce extremely high voltages. It can also supply higher current than most electrostatic high voltage generation devices.

Transformators for instrumentation

It is used to measure current and voltage within electrical power systems. Also used to monitor and control power system safety and performance. When a voltage/current is too large for an instrument to use, it can easily be brought down to a low, standard value.


Autotransformers tend to be lighter, more compact and less expensive than traditional dual-winding Transformers. On the other hand, an autotransformer is not capable of providing electrical isolation. Autotransformers have the ability to change between voltages in a 110-117-128 volt range as well as voltages in the 220-230-244 range. You can get 110V or120V output from 230V input. It allows equipment with 100 or 120V regions to be used in an 230V region.

Leakage transformers

A leakage or stray-field transformer has a higher leakage rate than other types of transformers. The leakage inductance can sometimes be increased with a magnetic bypass or thrust between primary and secondary. These are adjustable with a set wrench from time to time. It is used principally for high voltage discharge lamps (arc welding) and arc welding. It is used for both voltage and magnetic ballast.

Polyphase transformers

Polyphase Transformers provide three-phase electricity. These Polyphase transformers combine the magnetic circuits together. The core then holds three-phase flux. There are many different winding configurations available that give rise to different attributes or phase shifts. The main purpose is to ground and suppress harmonic currents.

Audio transformers

Audio transformers have been specifically developed for audio circuits. They can be used for blocking radio frequency interference or the DC part of an audio message, to divide or merge audio signals, or supply impedance matching between high impedance and low impedance networks. Such transformers were used in the past to connect telephone systems. However, they can be used to keep their power supplies isolated.
