Air cored series & Shunt Reactor, Upto 2 MVA , Upto 33Kv,
ONAN / AN
A variable transformer, reactor having a core combining at
least two complete core elements with a common yoke; primary
winding divided into two independently fed sets of phase
coils wound in opposite direction, arranged on symmetrical
legs of core elements and separated by the common yoke;
secondary winding with each phase coil divided into two
wound in opposite direction portions carried by symmetrical
core legs, adjacent to the primary coils and separated by
common yoke. The secondary short-circuited reactor winding
is reduced to at least one close loop member with loop
portions separated by the common yoke. The single, poly
phase apparatus has at least one primary coil per set that
includes a controllable device in circuit relation therewith
to enable control of one primary coil relative to the other,
either in current magnitude or in current phase shift. The
controllable device being either a silicon control rectifier
or transistor.
