What is the relation between line and phase quantities in both star and delta?
In the case of the Star Connection, the Line Voltage is √ 3 times the Phase Voltage, but the Line and Phase Currents are the same. Whether a Star or Delta Connection is used, the same formula (below) is applied to a 3 phase circuit: P = √ 3 x line voltage x line current times cos ø (power factor).
What is the difference between line to line and line to neutral voltage?
In a Single-Phase Supply system, the lower voltage (typically 120V) will be the ‘Line to Neutral Voltage’ which is the voltage between one of the lines and the neutral. The higher voltage (typically 240V) will be the ‘Line to Line Voltage’. The higher voltage (typically 480V or 600V) will be the ‘Line to Line Voltage’.
What is the difference between phase and line voltage?
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. For example, for a 208/120 volt service, the line voltage is 208 Volts, and the phase voltage is 120 Volts.
What is the relationship between line voltage and phase voltage?
Line voltage and Phase voltage Relation. Line voltage and Phase voltage are directly proportional to each other. When the line voltage increases, the phase voltage will also increase. When phase voltage increases, it will be reflected in the increase in line voltage.
What is the potential difference between one phase and three phase?
In three phase system, the potential difference between one phase to natural point is called phase voltage. It is denoted by V ph volts Phase voltage = Line voltage divide by 1.732 Phase current is the measure of the current inside of star connection or delta connection of the three phase system.
What is the magnitude of line current of your phase?
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 I L. ∴ I R = I Y = I B = I L, Where, I R is line current of R phase, I Y is line current of Y phase and I B is line current of B phase.
What is the difference between phase current and line current?
The three conductors R, Y and B are running from the three junctions known as Line Conductors. The current flowing through each phase is called Phase Current (Iph), and the current flowing through each line conductor is called Line Current (IL).
