What Are Line/Load Reactors?

Line/load reactors are inductors; coils of wire that oppose the flow of alternating current and limit the current that can flow through the circuits into which they are placed. They are used in two principal applications. Load reactors are generally used with motors circuits (load side of a motor drive), while line reactors are used […]

The Basics of Sine Wave Filters

Motors that operate on alternating current need special power supplies that can deliver power to start and stop the motor smoothly. For example, a motor driving a large fan used in an HVAC system would put undue stress on the mechanical parts of the fan if it were to transition from full “off” to full […]

Power Quality Solutions: Wind Energy

  About Wind Energy Thanks to the sun’s heating effect upon the Earth, the atmosphere is in a continual state of moving and mixing. Every cubic foot of air weighs about 1.3 ounces; when that air moves, it exerts force on obstacles in its path when it moves as wind. Wind turbines leverage this aerodynamic […]

Power Quality Solutions: Solar Energy

NASA estimates the sun converts nearly four million tons of matter to energy every second. The portion that reaching Earth’s upper atmosphere equates to about five pounds converted each second, which is equivalent to about 1,367 watts per square meter. The entire earth receives about 174,000 terawatts (TW) of solar radiation at the upper atmosphere. […]
