How is the phase of an alternating quantity represented?
How is the phase of an alternating quantity represented?
In both cases the phase angle and direction remains the same. The phase of an alternating quantity at any instant in time can be represented by a phasor diagram, so phasor diagrams can be thought of as “functions of time”.
How to calculate the relationship between line current and phase current?
In Delta, Vphase = VLine. Where as in Star Connection Vphase = VLine/sqrt (3). In Star, Iphase = ILine. Where as in Delta Connection Iphase = ILine/sqrt (3). ILine = Sqrt (3) * Iphase.
What is the name of the three phase connection?
Three phase voltage or star connection generally consists of voltage flowing through three different channels, for our simplicity we name it Voltage in the red line (V R ), Voltage in Yellow line (V Y ), the voltage in blue line (V B ). The voltage in all three channels is equal. Mathematically given as-
What is the phase relationship in an AC circuit?
Phase Relationships in AC Circuits. Phase. When capacitorsor inductorsare involved in an AC circuit, the current and voltage do not peak at the same time. 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.
What is the relation between phase and line?
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 (I L ).
In both cases the phase angle and direction remains the same. The phase of an alternating quantity at any instant in time can be represented by a phasor diagram, so phasor diagrams can be thought of as “functions of time”.
How are phase voltages and currents related in a balanced star system?
In the balanced star system, magnitude of phase voltage in each phase is V ph. ∴ V R = V Y = V B = V ph 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.
How are phase current and line current related in Delta Connection?
Relation Between Phase Current and Line Current in Delta Connection To obtain the delta connections, a 2 is connected with b 1, b 2 is connected with c 1 and c 2 is connected with a 1 as shown in the above figure. The three conductors R, Y and B are running from the three junctions known as Line Conductors.
