What is the difference between phase current & line

For a delta connection that is configured as a DAC where the Line-A current is equal to phase-a minus phase-c, the line current will lag the phase current by 30-degrees and the magnitude will be [math]\sqrt{3}[/math] times the phase current.

Voltage and Current Phasors in Three-Phase Systems

Key Difference: Current is the flow of electrons that pass through two voltages at different points. Voltage is the electric potential between two different points. Voltage is the electric potential between two different points.

Voltage and Current Phasors in Three-Phase Systems

Discuss the phase relationship of voltage and current in resistive, The difference between the peak positive value and the peak negative value is called the peak-to-peak value of the sine wave. This value is twice the maximum or peak value of the sine wave and is sometimes used for measurement of ac voltages. The peak value is one-half of the peak-to-peak value. 12.2.3 Instantaneous Value

Voltage and Current Phasors in Three-Phase Systems

The difference between the peak and valley in a 2-phase motor can be as great as 29%, while a 5-phase is only about 5%. Since torque ripple contributes directly to vibration the 5-phase motor runs smoother than the 2-phase.

6 Rebirth of the Phase Comparison Line Protection Principle 2. Phase Comparison Schemes 2.1. Basic principles Protection engineers are familiar with current differential protection, in which all the currents entering and leaving the zone of protection for a phase are summed. Normally the sum equals zero according to Kirchoff’s current law. A fault in the zone yields a nonzero sum equal to

Y configuration I phase = I line V phase < V line Delta configuration V phase = V line I phase < I line. Follow-up question: how do Kirchhoff’s Voltage and Current Laws explain the relationships between unequal quantities in “Y” and “Delta” configurations?

difference between line current and phase current pdf

What is the relationship between a phase current and a

When an AC current flows through a resistor, the voltage and current are in phase. However, when you introduce inductance or capacitance, a phase shift occurs and the phase angle depends on the amount of inductive and capacative reactance.

budgeting and forecasting techniques pdf

Quantitative techniques of forecasting are best used when changes are infrequent. In today's world of rapid change, quantitative techniques tend to be of little use. We need to add more qualitative techniques into the budgeting process. Qualitative techniques include surveys, interviews with people who are "in the know", market reports, articles, and other information sources that allow us to
