WHAT KIND OF EQUIPMENT CONTRIBUTES TO LOW POWER FACTOR?
There are many types of electrical appliances and equipment that can contribute to low Power Factor, some of which include:
Air Compressors
Air Conditioning
Automatic Doors
CD / DVR Players
Clocks
Computers
Conveyors
Copiers / Printers / Fax Machines
Elevators / Escalators
Fans
Fluorescent Lighting
Hand Power Tools
Heating Systems
Industrial Machinery
Microwaves
Powered Rollup Doors
Pumps
Refrigerators / Freezers
Robotic Machinery
Shredders
Transformers
Vacuum Systems
Ventilation Systems
Washers / Dryers
An understanding of how electrical power is consumed by appliances in a circuit is essential to understand how this product works.
Types of loads and their electrical behavior
Theoretically, there are three basic types of loads in an electrical system, e.g., resistive, inductive, and capacitive.
In Resistive Loads (example - oven, light bulbs, iron, electric heaters, etc.) the electrical energy delivered to resistive appliances is almost completely consumed by the appliance.
While electrical energy is consumed in pure resistive loads, electrical energy is not completely consumed in pure inductive and capacitive loads.
The electricity delivered to a capacitive or inductive appliance that is not consumed can, and should, be stored for future use.
