·Load Classification

In accordance with the nature of the load: resistive load, inductive load, capacitive load.

Resistive load: the load current compared to power when there is no phase load voltage is resistive (such as the load for the white flag lights, electric stove).

Inductive load: the load current when the load voltage is a phase lag when the load is inductive (such as the load motors, transformers).

Capacitive load: the load current when the load voltage of a phase advance is capacitive (such as the load for the compensation capacitor).
