Line Reactors

In situations where you have inverter drives located very close to the incoming facility power source, such as a substation, they may be susceptible to any incoming spikes and other transients. This is because there may not be enough impedance (in the form of transformers, power feeders, and the like) to help counteract these transient voltage spikes. This situation can damage the front end (diode section) of the drives or cause nuisance overvoltage tripping on the system. Installing a 5% impedance line reactor at the input to each drive helps counteract line spikes, keeping them from tripping or damaging the drives.

We stock the majority of sizes of Line reactors, we can ship Next Day if required.
