Differences between Shunt Reactor and Power Transformer

Jan 30, 2020 · Since a Shunt Reactor magnetizing current is large, if it is designed with Iron alone as a Power Transformer, there will be large hysteresis loss. Air gaps in Iron core are provided in a Shunt Reactor to reduce this loss and to minimize the remanent flux in the core. Thus a Shunt Reactor may also be constructed without iron (air-core).
