A three-phase power system comprising a simple, low cost processor and associated software algorithms for determining true three-phase power factor without having to convert between wye and delta configurations and without having to employ trigonometric calculations or having to measure phase. The ...
This also determines the measurement circuits for determining electrical power. Three-phase current systems often use the star or Y configuration. The three windings (L1, L2, L3) are connected to a common point in the motor. This "common star point" was led out into the junction box and ...

Since relays measure voltage and current values, the power factor can also be calculated. As a result, apparent (S), real (P) and reactive (Q) power can be derived from current and voltage measurements. The three phase and per phase relationships between the voltage (V), current (I), ...
