Line to Line Voltage Calculator:
Enter the value of phase voltage, PV(V) to determine the value of line-to-line voltage (VL-L).
Line to Line Voltage Formula:
Line-to-Line Voltage in electrical engineering is a critical measure for assessing the quality of power distribution in three-phase systems.
It helps in understanding the ability of an electrical system to provide consistent voltage levels from one phase to another despite load variations.
This is especially important in industrial settings where equipment sensitivity can dictate operational reliability and efficiency.
Line-to-line voltage, (VL-L)(V) in volts equals the square root of three times the phase voltage, PV(V) in volts.
Line-to-line voltage, VL-L = √3 * PV(V)
(VL-L)(V) = line to line voltage in volts, V.
PV(V) = phase voltage in volts, V.
Line to Line Voltage Calculation:
- Calculate the line-to-line voltage for a system with a phase voltage of 120 volts: Given: PV(V) = 120V.
Line-to-line voltage, (VL-L)(V) = √3 * PV(V)
(VL-L)(V) = √3 * 120
(VL-L)(V) = 1.732 * 120
(VL-L)(V) = 207.84V.
- Calculate the phase voltage if the line-to-line voltage is 380 volts.
Given: (VL-L)(V) = 380V.
Line-to-line voltage, (VL-L)(V) = √3 * PV(V)
PV(V) = (VL-L)(V) / √3
PV(V) = 380 / √3
PV(V) = 219.35V.
Applications and Considerations:
- Industrial Applications: Line-to-line voltage calculation is crucial for designing and maintaining three-phase electrical systems in industrial environments.
- Power Quality: Ensures that power quality is maintained, preventing equipment malfunctions or failures due to improper voltage levels.
- System Design: Critical for electrical engineers when planning the layout and voltage requirements of new electrical installations.
