Types of Electrical Loads for Power Inverter

1. Resistive Loads

– Resistive loads are loads which consume electrical energy in a sinusoidal manner. This means that the current flow is in time with and directly proportional to the voltage.

– It is a load that contains no inductance or capacitance, just pure resistance. Therefore; when a resistive load is energised, the current rises instantly to its steady-state value without first rising to a higher value.

– It includes loads such as incandescent lighting and electrical heaters.

2. Inductive Loads

– An Inductive Load is a load that pulls a large amount of current (an inrush current) when first energised. After a few cycles or seconds the current “settles down” to the full-load running current.

– Inductive loads can casue excessive voltages to appear when switched.

– Examples of Inductive Loads are motors, transformers, and wound control gear.

3. Capacitive Loads

– A Capacitive Load is an AC electrical load in which the current wave reaches its peak before the voltage.

– Capacitive loads are loads that capacitance esceeds inductance.

– Example of a Capacitive Load is the flash of the camera.
