is an absorber of reactive power, thus increasing the energy efficiency of the system. It is the most compact device commonly used for reactive power compensation in long high-voltage transmission lines and in cable systems. Shunt reactors are used in power systems to counteract the effect of the line parasitic capacitance, thereby stabilizing the system voltage within acceptable limits.
The conditions/ environment of operation of shunt reactor are not the same as it was a few decades ago owing to the dynamism of this market. Shunt reactor market is constantly evolving thus facilitating development of new technologies. Low transmission power lines combined with growth of renewable energy are the major drivers for this industry.
Dry type Reactors are constructed as single phase units and are thus arranged in a fashion to minimize stray magnetic field on surrounding (in the absence of metallic shielding). When such an arrangement is difficult, some form of magnetic shielding is required and designed with care to minimize eddy current loss and arcing at any joints within the metallic loops. One of the advantages of dry type reactor is absence of inrush current. Oil immersed reactors can be core-less or with gapped iron core. These are either single phase or three phase design with or without fan cooling. These are installed within tanks which hold oil & act as metallic magnetic shields.
Extra-high-voltage (EHV) transmission lines are employed to transmit power over vast distances; due to the long lengths, these lines have large shunt capacitances associated with them. Shunt capacitance exists between the individual phases of the transmission line and also between the phase conductors and ground. When a transmission line is energized, it draws a large charging current because of the large shunt capacitance of the line.The global market for Shunt reactor
