If you are given that the line to line voltage is 380V how do you calculate the voltage of each of the 3-phase's?
380V ÷ √3 = 219.4
How do you convert 3 phase RMS line-line voltage to RMS line-neutral voltage on an unbalance system Basically how do you calculate using trig for all 3 phase?
The term, 'unbalanced system' refers to an unbalanced load. Under normal circumstances, an unbalanced load leads to unbalanced line currents. The line voltages are determined by the supply and remain symmetrical, even when the load is unbalanced. As your question refers to a 'line to neutral' voltage (i.e. a phase voltage), you must be referring to a star (wye) connected load, in which case the phase voltage (line to neutral voltage) is 0.577 (the reciprocal of the square-root of 3) times the line voltage (line to line voltage).
What is a line to line voltage?
In a 3 phase system, the voltage measured between any two phase is called line to line voltage.And the voltage measured between line to neutral is called phase to neutral (line to neutral) voltage.AnswerThere is no such thing as a 'phase-to-phase' or a 'phase-to-neutral' voltage. The correct terms are 'line-to-line' and 'line-to-neutral'.The voltage between any two line conductors is called a line voltage.In a three-phase, three-wire, system, the line voltage is numerically equal to the phase voltage.In a three-phase, four-wire, system, the voltage between any line conductor and the neutral conductor is called a phase voltage. The line voltage is 1.732 times larger than the phase voltage.
How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
How do you calculate line regulations?
no load voltage - full load voltage by full load voltage
If you are given that the line to line voltage is 380V how do you calculate the voltage of each of the 3-phase's?
380V ÷ √3 = 219.4
How do you calculate line current?
Devide the wattage by the voltage
If you have a phase to phase voltage how do calculate the overall voltage?
First of all, there is no such thing as a 'phase-to-phase' voltage. The correct term is 'line-to-line' voltage. Secondly, without knowing what you mean by 'overall voltage', there is no way of answering your question.

How do you calculate current and voltage passing through light globes?
To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.
What is needed to calculate the voltage across a device?
you calculate a voltage circuit by taking it apart and findng the circuit and calculate the voltage and then resible it.
How do you calculate phase voltage of a three phase four wire system?
To calculate the phase voltage of a three-phase four-wire system, divide the line-to-line voltage by √3. In a balanced system, where the line-to-line voltage is given, the phase voltage will be the same for each phase. The formula is V(phase) = V(line)/√3.
How do you calculate the excitation voltage and current of an alternator?
formals to calculate exciation voltage of alternator
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
How far can power line be from house to pole without transformer?
It depends on the total load spread along the line and the voltage drop at full load at the end of the line. Generally up to 3 % voltage drop is considered ok. Anything beyond you need another transformer center.
How you calculate voltage drops in a cable knowing resistance or impedance and line current in a 3phase system?
Ohm's Law - V = IR.
