What is the relationship between phase and line voltage in a 3 phase generator?
The Voltage produced by the generator will be like 3 sets of your home's voltage (assuming we're looking at an outlet and not the 220V at the brkr box).Each phase (sinusoidal wave) will be separated by 120 degrees, so when the 1st phase starts the 2nd phase will start 1/20th of a second later. The 3rd phase then starts 1/40th of a second later, and the 1st phase starts again 1/60th of a second later which is the beginning of the second set of sin waves. This of course is based on the N. American Frequency of 60 hertz which is 60 cycles (waves) per second.AnswerFor a three-phase, three-wire, system the line voltages will be identical to the phase voltages.For a three-phase, four-wire, system the line voltages will be 1.732 times the value of the phase voltages.
What is is the formula for calculating the full load current of 23KVA generator?
to calculate the motor full load current one should know motor power factor, supply voltage and phase of supply. Assuming your motor is with 0.85 pf and 3 phase, 415V source then P = (Sqrt3)*V*I*pf 18500 = 1.732*415*0.85*I hence I = 30.2A
When are voltage and current out of phase?
Because the impedance of the inductor and capacitor is not a real resistance / has an imaginary value that causes voltage and current to be out of phase. An inductor's impedance is equivalent to j*w*L (j = i = imaginary number, w = frequency in radians, L = inductance), while a capacitor's impedance is 1/ (j*w*C). The 'j' causes the phase shift.
The phase angle between voltage and current in an a c circuit through a pure capacitance is?
90 degrees. In an AC circuit with a pure capacitance, the current leads the voltage by 90 degrees. This is because the current in a capacitor is proportional to the rate of change of voltage across it, leading to this phase relationship.
How do you calculate phase voltage of a three phase four wire system?
Phase voltage is determined by the wiring of transformer that serves the building. To test phase voltage use a volt meter and put one probe to ground and the other to each phase and observe the reading, this will give you a phase to ground voltage reading. Next test phase to phase (1 to 2, 1 to 3, and 2 to 3) to see if it's 208, 240, 277, or 480. Only licensed electricians should perform these tests. DAW
Does kva equal voltage x current x 1.73 for a 3 phase generator?
Yes, but only for balanced loads (current in all three phases the same value). The voltage value used is the phase to phase voltage.
How many amps for a 200 kva 3 phase generator working on 240 V per phase?
KVA means product of voltage and current. For 3 phase generator, its KVA = (1.732 X (Line Voltage) X Current)/1000.Put line voltage in this equation and get current.
What size of wire to use for 1015 kva ac generator?
To answer this question a voltage must be given to find the current output. Also whether the generator is three phase or single phase.
How do you convert line current to phase current?
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
What is the phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
AC circuit that contains both resistance and inductance will have a.The current and voltage in phase b.current will lead the voltage c.current will lag the voltage d.voltage will lag the current?
a. the current and voltage in phase
How to build a Rotary phase converter?
A simple Rotary phase converter is just a motor generator set. An electric motor running on the input voltage/current/phase/frequency. it drives a generator that supplies a different voltage/current/phase/frequency. So an electric motor and an electric generator connected together mechanically, either on the same shaft, or via gears, constitutes a Rotary phase converter. the above is incorrect, the motor/generator is the same motor, just one 3 phase motor is needed, it will run on T1 and T2, and put out L1, L2, and L3. You just need to know how to wire it up and what to do to get it to spin over on simple single phase 220, it will create three phase 220.
What is the formula use for calculation voltage and current in star and delta?
Balanced Star (Wye) Connected Systems:Line Voltage = 1.732 x Phase VoltageLine Current = Phase CurrentBalanced Delta Connected Systems:Line Voltage = Phase VoltageLine Current = 1.732 x Phase Current
Can a diesel generator for elevators run on single phase?
If the elevator has a single-phase motor, the diesel generator can also be single phase provided the voltage and VA ratings are compatible.
How many amps for 1010 KVA generator per phase?
To answer this question the voltage of the generator must be given.
How many kva is needed to draw 550A in a 3 phase generator?
The voltage of the generator needs to be stated to give an answer.
How power is flowing when voltage and phase angle is maintained same?
Assume you are saying that the current and voltage are in phase and you want to know how power is affected. When Voltage and Current are in phase the Power Factor is 1 and you have maximum power being applied. When Voltage and Current are not in phase, Power Factor decreases from 1 toward zero.
