Current Limiting Reactors
NWL is the leading manufacturer in North America of current limiting reactors (CLRs).
Overview
Current Limiting Reactors for Electrostatic Precipitators
The current limiting reactor is an inductor that is in the AC circuit of an electrostatic precipitator. They are sized to perform two functions, limit spark current to protect the other components in the circuit and to shape the AC sine wave. A CLR can be supplied as an open frame to fit back into a specific space, or with a NEMA rated enclosure, or as part of transformer rectifier set. NWL can also build current limiting reactors using either aluminum or copper windings. If the customer supplies the transformer ratings and either the inductance or percentage of impedance, NWL can design and manufacture the reactor with fixed or tapped values.
