application for single and three phase transformer?

Answer 1

3-phase transformers are almost exclusively used in industrial and business applications.

Factories, office buildings, power stations and sub-stations all use 3-phase power almost exclusively. Step down transformers take high voltage and step it down to 480 VAC (3-phase) for motors, heaters, lighting (after further step-down). Step-up transformers take power from generators and stepup the voltage very high for transmission to locations where the power is needed (cities, etc.)

1-phase transformers are used in residential power distribution applications. Step-down transformers step high voltage down to 240 Volts AC for home use.

Answer 2

Single phase transformers are normally used for house hold and small loads. The three phase transformer is used where large motors are in use. Large motor and large devices use 3 phse power. Lights are single phase, and small motors are single phase. Some large heaters are 3 phase also.

Answer 3

Single phase transformers are used for household applications.
Three phase transformers are used for Telecommunications, Transmission lines,Radar systems, Photocopying machines, Tool machines, Safety alarm and lighting plants, etc. For more : www.padmavahini.com

Answer 4

The three 260 MVA transformers may be connected in bank. Depending on the power supply voltage and the transformer primary winding rating, the primary may be connected in star or delta. Likewise the secondary may be connected either star or Delta as required for practical purposees.

Answer 5

three phase apps. are usually industrial.
