Why line current is same as phase current in star connection?
Relation Between Phase Current and Line Current in Star Connection. The same current flows through phase winding as well as in the line conductor as it is connected in series with the phase winding. Hence, in a 3 Phase system of star connections, the line current is equal to phase current.
What is the relation of line and phase values in star connection?
In star connection, line voltage is √3 times the phase voltage. In star connection, phase voltage is 1/√3 times the line voltage. For Delta connection, the line voltage and phase voltage are equal.
What is the difference between line and phase?
Terminology. The conductors between a voltage source and a load are called lines, and the voltage between any two lines is called line voltage. The voltage measured between any line and neutral is called phase voltage.
What is the relationship between line and phase current in star connection with the positive sequence?
In the balanced star system, magnitude of phase voltage in each phase is Vph. We know in the star connection, line current is same as phase current. The magnitude of this current is same in all three phases and say it is IL.
What is meant by same phase?
When the two quantities have the same frequency, and their maximum and minimum point achieve at the same point, then the quantities are said to have in the same phase. …
How do you find the phase difference in a circuit?
The fraction of a period difference between the peaks expressed in degrees is said to be the phase difference. The phase difference is <= 90 degrees.
How are the line and phase currents same?
The terms line current and phase current follows the same logic: the former referring to the current through any one line conductor, and the latter to the current through any one component. Y-connected sources and loads always have line voltages greater than phase voltages, and line currents equal to phase currents.
What is phase current?
Phase current is the current flowing through the phase to neutral. In case of star connection in a three phase system, line current and phase current are the same.
How to calculate line to line voltage?
How to Calculate Line-to-line RMS voltage? Line-to-line RMS voltage calculator uses rms_voltage = 0.8165*Input voltage to calculate the Root mean square voltage, The Line-to-line RMS voltage formula is the root mean square value of the line-to-line voltage of the inverter. Root mean square voltage and is denoted by Vrms symbol.
What is phase to phase voltage?
Answer / kiran. phase to phase and line to line voltage are same. Consider the voltage in R-phase or line=230V. Y-phase or line=230V. B-phase or line=230V. To calulate phase to phase voltage you have a formulae i.e., inputvoltage*root3(1.732)i.e., 230v*1.732=398.36v.
