What is the phase relationship between line current in Delta system?
In a delta system, the line current is greater than the phase current by the square root of 3, which is about 1.732). In a wye system, the line current equals the phase current.
How do you find the current in a delta circuit?
Line Currents (IL) and Phase Currents (IPh) in Delta Connection
- Current in Line 1= I1 = IR – I. B
- Current in Line 2 =I2 = IY – I. R
- Current in Line 3 =I3 = IB – I. Y
How do you calculate phase current from line current?
Line current to phase current calculator: Phase current I(P) in Amps is equal to line current I(L) in Amps divided by root 3. Example: Calculate the phase current of the delta connected alternator output line current of 1500 Amps. I(P) = 1500 / 1.732 = 866 Amps.
What is the relationship between the line current IL and the phase current I 1 in a balanced delta system?
Relation Between Phase Current and Line Current in Delta Connection. As in the balanced system the three-phase current I12, I23 and I31 are equal in magnitude but are displaced from one another by 120° electrical. Hence, in delta connection line current is root three times of phase current.
What is phase current and line current?
Line current is the current through any one line between a three-phase source and load. Phase current is the current through any one component comprising a three-phase source or load.
How do you determine Wye or Delta?
A wye system is connected in a “Y” shape, or configured in a star shape. In a delta system configuration, the phase voltage is equal to the line voltage. In a wye system configuration, the phase voltage is equivalent to the line voltage divided by the root of 3.
What is line current & phase current?
What is the relationship between the line current and the winding current of three phase wye connected transformers?
When windings are connected wye, the voltage between any two lines will be 1.732 times the phase voltage, and the line current will be the same as the phase current.
How do you find the current in a Delta Delta Connection?
Line & Phase Current and Line & Phase Voltage in Delta (Δ) Connection The current of Line 1 can be found by determining the vector difference between IR and IB and we can do that by increasing the IB Vector in reverse, so that, IR and IB makes a parallelogram.
Is line voltage equal to phase voltage in a Delta Connection?
The line voltages are: Hence, in delta connection line voltage is equal to phase voltage. Relation Between Phase Current and Line Current in Delta Connection As in the balanced system the three-phase current I 12, I 23 and I 31 are equal in magnitude but are displaced from one another by 120° electrical.
How many phase winding are there in Delta Connection?
It is seen in fig 2 that there is only one phase winding between two terminals (i.e. there is one phase winding between two wires). Therefore, in Delta Connection, the voltage between (any pair of) two lines is equal to the phase voltage of the phase winding which is connected between two lines.
What is the formula for power factor in Delta Connection?
Power in Delta Connection, P = 3 x V PH x I PH x CosФ …. or. P = √3 x V L x I L x CosФ. Where Cos Φ = Power factor = the phase angle between Phase Voltage and Phase Current (not between Line current and line voltage).
