Usually a detuning reactor has more inductance.

Detuned Reactor
Detuned Reactors prevent harmonic amplification caused due to RESONANCE and avoid the risk of overloading capacitors, thereby significantly reducing voltage and current harmonic distortion in the network. All connected equipment, and even remote substations are subject to voltage fluctuations which may result in equipment malfunction or failure. To avoid this problem, it is common to insert reactors in series with capacitor banks. The reactor also by its nature will safeguard capacitor and associated switch gears against switching inrush, which other may damage capacitors, circuit breakers and contactors. The inductance value of detuned reactor is selected such that the resonance frequency is less than 90% of dominant harmonic in the spectrum. For example: if 5th harmonic is dominant in the spectrum, any series LC circuit having resonance frequency 90% of 250Hz (for 50Hz system) ... i.e., if the natural resonance frequency of LC is less than 225Hz, it is categorized as detuned filters or detuned capacitors.
Line Reactor
Line reactors are placed in the power distribution side of the drive’s supply line. Line reactors help stabilize electrical currents when VFDs and other devices are in use. In addition, line reactors help reduce transients and harmonics which are harmful to the drive’s life over time. These reactors work as an impedance between the power source and VFD and as a result slow down harmonics and disturbances such as voltage spikes and surges. They can protect your VFD and extend its life in the process. Line disturbances and harmonics are common in many heavy-duty types of machinery and in machines where power is being switched on and off constantly. Take for example when a toilet Is flushed while the shower is running at the same time. Constant heavy loads like these with rapid changes can cause circuit breaks. With a line reactor installed this can eliminate these power surges and reduce circuits from tripping.
Load Reactor
Load reactors are used in the motor side of the drive’s load. They protect the motor by acting as a buffer when there is a long distance between the motor and VFD. As the drive generates high-frequency noises when it is initially turned “on”, it causes voltage spikes to occur. Load reactors can filter out noise caused by the motor and mitigate noise amplified through long cable lengths. Load reactors are recommended to be used only if motor wiring is more than 100 ft apart. For extreme distances, DV/DT filters should be used. DV/DT filters also help protect your motor by reducing voltage peaks from VFD devices. Their difference from load reactors lies in their ability to have a longer range of protection. They are commonly applied in systems such as conveyor belts, production lines, and many other machines/equipment with long lead lengths.
