Line Current Calculator
Enter the value of total phase current, IP(A) to determine the value of Line current, IL(A).
Line Current Formula:
Line current refers to the electric current that flows through any of the external conductors in a multi-phase (typically three-phase) electrical system.
This type of current is critical for understanding power distribution and load management in systems operating with three-phase power.
In three-phase systems, line current flows through the conductors that connect the power source to the load.
The line current is different from the phase current, which flows through any one of the three phases in relation to the neutral or ground in a three-phase system.
In a three-phase system, the line current is the current flowing through any one of the conductors to a load.
In balanced loads, the line currents are equal, whereas in unbalanced loads, the line currents can vary.
Line current, IL(A) in amperes is calculated by the product of total phase current, IP(A) in amperes and 1.732.
Line current, IL(A) = IP(A) * 1.732
IL(A) = line current in amperes, A.
IP(A) = total phase current in amperes, A.
Line Current Calculation:
- Calculate the line current for a system where the phase current is 10 amperes:
Given: IP(A) = 10A.
Line current, IL(A) = IP(A) * 1.732
IL(A) = 10 * 1.732
IL(A) = 17.32A.
- Determine the phase current if the line current in a delta system is 20 amperes:
Given: IP(A) = 20A.
Line current, IL(A) = IP(A) * 1.732
IP(A) = IL(A) / 1.732
IP(A) = 20 / 1.732
IP(A) = 11.54A.
