Why line current is greater than phase current in delta connection?
Because if you apply Kirchhoff's Current Law to the junction between the line current and the two phase currents, the line current is the phasor (vector) sum of two phase currents. For a balanced load (only), this works out to 1.732 x phase current.
How do you calculate the total input current from a 3-phase power source when the current from each phase is known?
Add them upAnswerThere is no 'total' current in a three-phase system. The current flowing in each line (not 'phase') is considered separately. And you most definitely don't 'add them up'!
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
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.
How to Calculate three phase watts with unbalanced phase current?
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.
Is rms is line current or phase current?
RMS (root mean square) value can refer to either line current or phase current, depending on the context of the electrical system being discussed. In a three-phase system, the RMS line current is the current flowing in the lines connecting the power source to the load, while the RMS phase current is the current flowing through each phase of the load. For balanced loads in a three-phase system, the RMS line current and phase current have specific relationships, but they are distinct concepts.
How do you zero phase current tranformer test?

When will there be any current in phase?
Current is always flowing in the phase due to the continuous voltage application. the current in phase can be used when it is given a - ve terminal or earth the current would complete the circuit.

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 proof line current is equal to square root of 3 times of phase currents?
In a three-phase system, the line current (I_L) and phase current (I_Ph) relationship can be derived from the configuration of the system. For a balanced load in a star (Y) connection, the line current is equal to the phase current (I_L = I_Ph). In a delta (Δ) connection, the line current is equal to the phase current multiplied by the square root of 3 (I_L = √3 * I_Ph) due to the geometry of the connections and the phase angle relationships, resulting in the factor of √3 that arises from the 120-degree phase shifts between the currents. Thus, for a delta connection, the line current is greater than the phase current by that factor.
What is current in three phase and single phase?
All current is the passage of electric charges from one terminal to another through a conductor so there is no real difference in the type of current that flows in a 3 phase system compared to a single phase system.
In delta connection what is formula for phase current?
Line current = 1.732 x Phase CurrentCommentOnly for balanced loads.
