How do you make a 3 phase electric meter?

Installation of 3 Phase kWh Energy Meter

  1. R = RED Phase / Live Wire from the source supply voltage.
  2. Y = YELLOW Phase / Live Wire from the source supply voltage.
  3. B = BLUE Phase / Live Wire from the source supply voltage.
  4. Line or IN = Incoming Phase / live or Neutral from the source supply voltage.

How is power measured on a 3-phase system?

In a balanced 3-wire, 3-phase load circuit the power in each phase is equal and, therefore, the total power of the circuit can be determined by multiplying the power measured in any one phase. Hence, the power measurement in three-phase, three-wire circuits can be carried out by using the one wattmeter only.

How does Arduino measure AC voltage?

For a 5 volt Arduino, the maximum value from the ADC will be 1023. Similarly, using the unitary method, we can calculate the voltage for the 1 division it shows: 1 = 5/1023 В. So for a value of 545 the division voltage = (5/1023) * 545 = 2.66 V. When the mains voltage is 227 VAC, the Arduino shows 2.66 V.

How do you measure power in 3 phase circuits using 3 and 2 wattmeter method?

Two Wattmeter Method can be employed to measure the power in a 3 phase, three-wire star or delta connected the balanced or unbalanced load. The total instantaneous power absorbed by the three loads Z1, Z2 and Z3, is equal to the sum of the powers measured by the two wattmeters, W1 and W2.
