Application
- Shunt Reactors to compensate for capacitive
VARS
- Current limiting Reactors
- Filtering Reactors
- Neutral Grounding Reactors
Air core reactors are designed
utilizing specifically developed Finite Element Analysis software.
Construction
Windings are
manufactured with aluminum or copper, (strip or shaped conductors
in parallel where necessary) arranged on layers or discs with special
consideration given to minimize the eddy losses. The insulating materials
used during production are always UL listed systems. To suit various
applications and environmental conditions Rex Dry Type Air Core Reactors
are manufactured using our Multiple VPI and Epoxy Impregnation system.
Alternately, for harsh conditions Rex offers Reactors that are solidly
cast in epoxy in special moulds under vacuum.
Reactors can be supplied either as single-phase coils individually
supported on insulators or alternatively as three phase coils stacked
vertically.
A variety of custom enclosure designs are available to sheild and
protect the reactors magnetically and environmentally.
 Tests
All tests are done
right on our premises to CSA, UL, and IEEE C57.16 requirements.
Routine Factory Tests:
- Windings resistance with direct current
- Impedance and losses
- Dielectric (HV voltage withstand) to ground
and between turns
Type Tests
- Temperature Rise
- Thermal Capability Calculation
- Impulse
- Mechanical Strength
