Homework Statement

sir am new technician my boss told me that to find 3 phase power without off the machine . i have single phase clamp meter can measure voltage and current . how to find total power.

Homework Equations

\sqrt{}3* V line *I line * cos$

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.
