EssentialPhasor

Concept: Different load types change the phase relationship between voltage and current. In this example, resistive loads are in phase (0°), while inductive and capacitive loads are shown lagging and leading by 30°, respectively. This illustrates how the power factor changes based on the type of equipment connected to the system.

Issue: If a current transformer's S1 and S2 connections are reversed (crossed), it reverses the phase angle of that phase by 180°. This creates an immediate imbalance visible in the phasor diagram. Toggle to see the difference between correct and reversed Phase B wiring.

Issue: If voltage phases B and C are swapped at the meter connection, the voltage sequence becomes reversed while currents remain correct. This creates a phase mismatch visible in the phasor diagram. Toggle to see the difference between correct and swapped voltage phases.

Concept: When solar panels generate power on all three phases, the current phase angles reverse by 180° compared to loads. Instead of lagging the voltage (negative angle), generated currents lead the voltage (positive angle). This shows the fundamental difference between consuming power and generating power in a 3-phase system.
