Explanation:
A 3 phase power system is a type of AC power system that consists of three phases, each of which is 120 degrees apart from the other two. In such a system, the voltage is measured in two different ways: phase voltage and line to line voltage.
RMS Line to Line Voltage:
The rated voltage of a 3 phase power system is given as RMS line to line voltage. RMS stands for Root Mean Square, which is a mathematical term used to describe the effective value of an AC voltage or current. The RMS line to line voltage is the effective value of the voltage measured between any two phases in a 3 phase power system.
Peak Line to Line Voltage:
The peak line to line voltage, on the other hand, is the maximum value of the voltage measured between any two phases in a 3 phase power system. It is usually calculated as the RMS voltage multiplied by the square root of 2 (1.414).
RMS Phase Voltage:
The RMS phase voltage is the effective value of the voltage measured between any one phase and the neutral point in a 3 phase power system. It is usually calculated as the RMS line to line voltage divided by the square root of 3 (1.732).
Peak Phase Voltage:
The peak phase voltage, which is the maximum value of the voltage measured between any one phase and the neutral point in a 3 phase power system, is usually calculated as the RMS phase voltage multiplied by the square root of 2 (1.414).
Conclusion:
Therefore, the rated voltage of a 3 phase power system is given as RMS line to line voltage because it represents the effective value of the voltage that is available for use in the system.
