3 Phase Converter

             Electric power can be used and transmitted as single, two or 3 phases electric system. While transmitting power 3 phases system is better due to the fact that it needs less conductor material; it is thus economical. In three phase system three conductors carry AC (alternating current) electric current at the same frequency but one lags the reference current by one third of a cycle and other lags the reference by two thirds of a cycle. This helps to give constant power at each cycle and provide rotating magnetic field in an electric motor. A neutral wire in 3 phases system has neutral wire in order to supply power to one phase system. In high power transmission line there is no neutral line. The 3 phase electric system has the following advantages over the one phase electric system:

                        . Balanced load

                        . Rotating magnetic field makes AC motor design simple

                        . Balanced load helps to reduce vibrations

            Because of the above advantages 1 phase system users get '3 phase converter' to get 3 phase AC (Alternating Current) power from one phase service. Most of the rural areas have one phase electric power service and has no access to 3 phases service. In that case a '3 phase converter' is the solution if rural users want 3 phases electric power. Some of the urban households have one phase service and may not have access to 3 phases service or the 3 phases is not economical. These urban users can use 3 phases converter to satisfy their 3 phase electrical power needs.

            It is possible to buy service guidelines and electrical diagrams to convert a one phase to 3 phases electrical power system. But because of safety issues and complexity, and risks of failure it is advisable to by professionally made 3 phase converters. Two types of 3 phase converters are available in the market: Rotary Phase Converter, Static Phase Converter. It is generally recommended that 3 phases converter should be used instead static converter.

            The US Phase Converter Standards organization provides important information regarding 3 phase converters. It also provides a resource page for good 3 phase AC converter companies.
