Abstract
PURPOSE: To make possible converting equivalent power factors to d.c. voltage in a circuit manner without using any intricate measuring elements by measuring the sum of the phase angles of differential current and differential voltage between the respective two phases of a 3-phase circuit, and letting the sum of these phase angles be a measure of equivalent power factors or the phase angles corresponding to equivalent power factors.
