3-phase, 3-wire a.c. system.formulaHello! How can I assist you today?
In a 3-phase, 3-wire AC system, the power is transmitted using three live wires and one neutral wire. The three live wires are typically labeled as R, Y, and B, representing the three phases of the system.3-phase, 3-wire a.c. system.formula
Single phase 2-wire system formulaIn a 3-phase, 3-wire AC system, the power is transmitted using three live wires and one neutral wire. The three live wires are typically labeled as R, Y, and B, representing the three phases of the system.
To calculate the power in a 3-phase system, you can use the following formula:
Power (P) = √3 × Voltage (V) × Current (I) × Power Factor (PF)
Where:
- √3 is the square root of 3, approximately equal to 1.732
- Voltage (V) is the line-to-line voltage in volts (V)
- Current (I) is the line current in amperes (A)
- Power Factor (PF) is the ratio of real power to apparent power (dimensionless)
It's important to note that the above formula calculates the apparent power (VA). To determine the real power (Watts), you would need to multiply the apparent power by the power factor.
Additionally, if you are looking to calculate the power per phase, you can divide the total power by 3 since the power is distributed equally among the three phases.
I hope this helps! Let me know if you have any further questions.
In a single-phase, 2-wire system, the power is transmitted using two wires: one live wire and one neutral wire. This type of system is commonly used for residential and small commercial applications.Single phase 2-wire system.

3-phase, 3-wire a.c. system power loss formulaIn a single-phase, 2-wire system, the power is transmitted using two wires: one live wire and one neutral wire. This type of system is commonly used for residential and small commercial applications.
To calculate the power in a single-phase, 2-wire system, you can use the following formula:
Power (P) = Voltage (V) × Current (I) × Power Factor (PF)
Where:
- Voltage (V) is the line-to-neutral voltage in volts (V)
- Current (I) is the line current in amperes (A)
- Power Factor (PF) is the ratio of real power to apparent power (dimensionless)
The power factor represents the efficiency of the system and can be a value between 0 and 1. A power factor of 1 means the system is operating at maximum efficiency, while a power factor less than 1 indicates some inefficiencies.
It's important to note that the above formula calculates the apparent power (VA). To determine the real power (Watts), you would need to multiply the apparent power by the power factor.
I hope this clarifies the calculation for a single-phase, 2-wire system. Let me know if you have any further questions.
