Load reactors are generally used with motors circuits (load side of a motor drive), while line reactors are used in power distribution (line side of a drive). The reason line/load inductors can limit current is based on a principle known as reactance.Jul 21, 2015
How do you select a line reactor for a VFD?
- Insulation class – look for 200⁰ C insulation or better.
- Expect a minimum of a 115⁰ C heat rise.
- Ask for VPI (vacuum pressure impregnation) construction.
- Reactors should be designed for both line and load side use, with no de-rating.
How do line reactors work?
A line reactor is an inductor that absorbs high voltage microsecond transients that can damage the Variable Frequency Drives running your facility. Line reactors achieve this by slowing the rise time of the voltage spike to keep your VFDs safe.Apr 27, 2017

Can you oversize a line reactor?
With that in mind, it is important to avoid oversizing the line reactor for the load current of the application. When applied to the input side of a variable frequency drive, the applied impedance of the reactor will work to soften and slow down incoming line voltage distor- tion such as spikes and surges.
Can a line reactor be used as a load reactor?
Line reactors can protect the entire VFD from power system surges and transients. ... When a reactor is connected in series between the VFD and motors, it is referred to as a load reactor, which helps protect motors like an energy buffer.
