single phase
Single-phase electric power is when all the voltages of the supply vary in unison. Single-phase meaning power lines as an input source; therefore, only primary and secondary winding is required to accomplish the voltage transformation. In electrical engineering, single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors. Single-phase transformers are used to supply power for residential lighting, receptacle, air-conditioning, and heating needs. A transformer with a 120 volt AC secondary can take care of the lighting and receptacles. Most household loads are single phase. In Canada, US and some other countries, three phase power generally does not enter homes. Even in areas where it does, it is typically split out at the main distribution board and the individual loads are fed off a "single" phase. When single-phase electricity is needed, it is available between any two phases of a three-phase system, or in some systems, between one of the phases and ground.
Basic single-phase transformer more versatile, both the primary and secondary windings are made in two equal parts. The two parts can be reconnected either in a series or in parallel. This provides added versatility as the primary winding can be connected for either 480 volts or 240 volts and the secondary winding can likewise be divided into two equal parts providing either 120 or 240 volts. (note: there will be four leads per winding brought out to the terminal compartment rather than two). either arrangement will not affect the capacity of the transformer. Secondary windings are rated with a slant such as 120/240 and can be connected in a series for 240V or in a parallel for 120V or 240/120V (for 3-wire operation). Primary windings rated with an X such as 240X480 can operate in series or parallel but are not designed for 3-wire operation. A transformer rated 240x480V primary, 120/240V secondary could be operated in 6 different combinations. Copper and aluminum are used for transformer windings. These materials are available in a variety of grades and thickness, each with their own efficiency characteristic. Winding losses, or load losses, arise from the conducting material's inherent resistance to the flow of electrical current. Winding losses increase with the square of the transformer load. Efficiency gains can by achieved by using materials with lower resistively or greater diameter. For example, coils make with copper can have considerably lower load losses than those make with other materials. Data based on popular 45 kVA size shows $1000/ year savings. That is $10,000 saved over ten years. Please choose Aluminum or Copper conductor coil transformer. |
