SUMMARY
The discussion centers on calculating three-phase power without disconnecting the load using a single-phase clamp meter. The key formula presented is √3 * V_line * I_line * cos(φ), where voltage and current measurements are taken from each line. The user suggests measuring the power across two phases (P1 and P2) and combining the results to estimate total power. It is established that at least two meters are necessary for accurate three-phase power calculations.
