Types of Transformer

Different types of transformer are audio transformer, fly back transformers, power transformer, push-pull transformer, current transformer, Electric transformer, Isolation transformer, step up transformer, and step down transformer.

Electric transformer is a device used to transfer an alternating current or voltage from one circuit to another circuit by way of electromagnetic induction. The simplest kind comprises of two coil of wire, insulated from one another and arranged to change the current in one coil would in turn produce a change in voltage in the other coil. A current transformer is a kind of electrical instrument that is produced particularly to provide a flow of current in the secondary circuit that is properly perpendicular to the amount of current flowing in its primary circuit. A high voltage transformer are generally used in power transmission applications, where voltages are very high sufficient to present a safety hazard.

Isolation transformer is a kind of current transformer which is used to supply power for equipments. Isolation transformer was designed specially by the manufacturers to meet the requirements of the business people and general users around the world for affordable prices. Low voltage transformer can be used as a magnetic low voltage transformer or electronic transformer. Low voltage transformers are mainly produced to reduce 120 volt line voltage to the secondary or the output voltage of the 12 volts. Fly back Transformer may be defined as an integrated transformer which implies it has built in rectifiers and divider networks and several low voltage windings.
A fly back transformer that is also called as a line output transformer is a kind of transformer used in the power supply of a cathode ray tube that generates the high voltage required ranging from a few kilo vats for an oscilloscope tube to 20 to 30 kv needed for a color TV tube. Audio transformers play an important part of any audio equipment. They are used for voice communication only. They operate from 200 Hz to 500 Hz. Audio transformers have different rated DC current. The main object of audio transformers is to make the quality of sound better by reducing the interference of audio signals. Single phase power distribution normally works great with rural areas, where the cost of the three-phase power distribution network is extremely high and in turn the motor loads are small and unusual as well. Larger clients like large buildings, shopping malls, factories, workplace blocks, and various unit apartment building blocks would have three phase service
