Remark :
* When the Reactive power value ( Q1 to Q3 ) show " - "
indicator, it means the " current phase " lag than the " voltage
phase ", the load character is induction.
* When the Reactive power value ( Q1 to Q3 ) do not show " - "
indicator, it means the " current phase " lead than the " voltage
phase ", the load character is capacitance.
