    1. The problem statement, all variables and given/known data

    sir am new technician my boss told me that to find 3 phase power with out off the machine . i have single phase clamp meter can measure voltage and current . how to find total power.

    2. Relevant equations
    [tex]\sqrt{}3[/tex]* V line *I line * cos$

    3. The attempt at a solution
    find all the current and voltage on each line find average use equation

    I know that you need at least two meters to get 3 phase power.
    you put P1 from a to b wires and P2 from b to c.

    power is equal to P_meter1 + P_meter2
    and Q is sqrt(3) {P_meter1-P_meter2} I think

    You should google finding three phase power.
