What is an AC line reactor? AC line reactors are added to the input of the drive and placed in series with the incoming line. They help to mitigate harmonics and because they are between the line and the drive, they are able to act as a buffer for surges and other transients.
What does a line reactor do?
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
When would you use a line reactor on a VFD?
- Line side is prone to surges, transients and harmonics.
- If VFD devices are being used in the circuit.
- Total Harmonic Current distortion (THID) drive exceeds 5%
- Turning on heavy-duty equipment or machines going through heavy loads.
What is a line load reactor?
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. ... That opposition to current flow through the coil is known as inductive reactance.Jul 21, 2015
What does a 3 phase line reactor do?
Three-phase reactors intended for the attenuation of notches and spikes, reduction of harmonics and limitation of inrush currents in converters and variable speed drives. Drop voltage of 4% of the rated voltage (400V). Manufactured with electrical steel with low losses and copper windings.
What is the difference between a line reactor and a load reactor?
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

What is reactor and its function?
A reactor is a coil which has large number of turns and whose ohmic resistance value is much greater. Reactors are used to limit the short circuit currents which can cause damage to the equipments of the power system. ... They are used to limit the short circuit currents according to the capacity of circuit breakers.
What is reactor in power system?
A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes. Reactors may be tapped so that the voltage across them can be changed to compensate for a change in the load that the motor is starting.May 3, 2021
What is difference between reactor and transformer?
Main Differences. Shunt Reactor and Transformer both appear similar in construction. ... While a Power Transformer is designed for efficient power transfer from one voltage system to another, a shunt reactor is intended only to consume reactive VArs (or in other words it can be stated as to produce lagging VArs).Sep 18, 2012
