On a Delta 3-phase you connect the single phase loads between pairs of the 3-phases. Warning both sides of these loads will be hot! You may want to use 3 isolation Transformers so that the real loads have a neutral line.
On Y 3-phase you connect the single phase loads between one of the 3-phases and neutral.
In each case to balance the loads, try to put similar loads on each phase (or pair of phases).
Today's three phase systems are three phase four wire systems. The reason to try and balance any single phase load connected to a three phase four wire system is to reduce the current draw on the neutral conductor. The neutral carries the unbalanced load current. The closer that you keep the single phase loads balanced the lower the neutral current becomes. On a perfectly balanced three phase load there is no neutral current.

What is the volt drop across a 10k resistor with a 5 volt supply?
If there is nothing else in the circuit, then the voltage drop across the resistor will be the full supply voltage of 5 volts. The size of the resistor does not matter in this case - it will always be 5 volts.
What is static converter can a power supply of computer is static converter?
A single phase supply can operate a three phase motor with a static converter. No a power supply of computer cannot be fed through the static converter.
What would cause a meter to read negative voltage across a DC motor?
A DC motor generates power when it is rotating even when no supply is connected.
Why does voltage change across components but not current?
we know,v=IRresistor, capacitor, inductor and other electrical components have their own specific characteristics to drop voltage or to consume voltage at a fixed amount.the supplied voltage produces a current that changes with the change of the voltage. It doesn't changes simultaneously. so the voltage change across the components. but the current doesn't changes across component...AnswerThink of a circuit with several loads as being rather like a number of central heating radiators connected in the same way. The same water (current) flows through each radiator. In order for that water to flow, we need a pump to supply pressure (supply voltage) across all the radiators. At the same time, there must also be a pressure difference (voltage drop) across each individual radiator or the water wouldn't flow through it. The sum of these individual pressures must add up to equal the pressure supplied by the pump.So the same current flows through individual loads, driven by the supply voltage applied across the entire circuit. At the same time, there must also be voltages across individual loads (called 'voltage drops'), or current wouldn't be flowing through them. The sum of the individual voltage drops will equal the supply voltage.
What are the safety precautions for the electronic balance?
Safety precautions that individuals should follow for electronic balances are to make sure users have the right voltage and to make sure that they have the correct power supply. Failure to do this can lead to harm.
Is 10 kva supply to 3 phase load is equal to 10kva supply to single phase load?
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
How convert 1 phase to 3phase in aircraft?
The power is generated in the form of three-phase in aircraft, and this sytem has no problem in feeding single phase loads. To conserve mass in tansformers and motors the supply works at 400 Hz.
Can i run single phase dc motor from 3phase bldc controller. i m using single phase motor in motorcycle and controller from other electric vehicle. if yes please tell me how to connect it?
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
What is the electricity in Africa?
Across the whole of Africa the domestic supply is single phase 50Hz and in the range, depending on country, from 220 to 240 Volts.
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
How do you get half of the voltage from a DC supply circuit?
By using a voltage divider, that is two resistors of the same value in series across the DC supply. Half of the supply voltage will be at the point where the two resistors is connected. But how much wattage of those resistors is also an issue.
What is expension of supply?
supply expansion refer to the situation where the supply for a particular product is increase across geographical boundary.
What is the function of capacitor across the supply to the fluorescent lamp when it is used?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
When would a three phase supply be preferred over a single phase supply?
Bcoz in single phase if supply is interrupt or any trouble there is no power .but in 3 phase if 1phase supply gone we can manage it by other 2 phases
What do single sugars supply to cells?
ENERGY
What conditions would change supply and demand?
The economic condition of the area is a condition that can change the balance between supply and demand.
What is a protective resistor?
The protecting resistor is put in series with the LED so that you have a voltage divider - the supply voltage is split across the LED ( max 0.6v) and the remainder across the protecting resistor. So if your supply is 6volts, 5.4v will be across the resistor,
