If you have single phase now, you have two options. One, is to install a three phase service or Two, install a roto phase device.
STAR connection is best suit for 3 phase 4 wire seviceas there is a neautral wire is there in this connection
i think its use for 3 phase connection.
The Scott T Connection is what you are considering. There is an article in wikipedia.org, but they say there that this concept is of historic importance only.
To terminate a 3 wire wye motor to a 3 phase delta connection you need a 3 phase transformer to convert from delta to wye. Do not lift the common neutral connections inside the motor and rewire for delta, because the voltages will be wrong.
Because that is the simplest, cheapest and most efficient way to do it.
Single phase connection has 1 phase wire and a neutral wire. Another wire for protective earth. In three phase system, motor can be connected in star or delta. Most AC induction motors are in Delta. Power distribution system is generally 3 phase 4 wire. Transmission system is 3 phase high voltage. Industry uses 3 phase system, where as 1 phase is for domestic, commercial applications. Both 1 and 3 phase system has a frequency. It is either 50 Hz or 60 Hz, depending upon the country or region.
In a three-phase electrical system, there are typically three live (or phase) wires and usually no neutral wire is required for balanced loads. However, if the loads are unbalanced or if a neutral is needed for specific applications, a neutral wire can be included. This allows for the connection of single-phase loads. Overall, the standard three-phase connection primarily consists of the three live wires.
A connection can be taken between phase lines, or between one phase and neutral. Both methods give a single-phase supply. Between phases the voltage is sqrt(3) times more than between one phase and neutral. In each case the load gives an unbalanced current on the 3-phase system but the idea is to average out the unbalances over a group of single-phase loads.
its simple: its either single phase or three phase connection
It depends on the 3 phase inverter. If it is a 3 phase input then you will first need to get a single phase to 3 phase converter to simulate a 3 phase supply, if that is what this particular inverter is intended for then you will have a label saying 230v primary with a L & N connection point, and the output will be labelled as secondary, giving you the inverted power rating. This is a very expensive way of running machinery as the inverted power is no different in conumption to the single phase.
A delta connected appliance can be connected to a 3-phase system by leaving the neutral unconnected. The appliance must be properly earthed.
