Medium-voltage power
factor correction
Product description
Eaton’s metal-enclosed medium-voltage capacitor
systems and detuned filters are designed for
indoor or outdoor applications in a wide variety of
power systems requiring power factor correction
and can increase system capacity . Designs are
available with a host of options and accessories
to fit the requirements and desired configurations
of virtually any installation . Multi-stage metal-
enclosed medium-voltage capacitor banks
are designed for systems such as industrial,
commercial, and utility power systems involving
motors, feeder circuits, and transmission and
distribution lines where power factor improvement
is required .

Metal-enclosed medium-voltage
power factor correction system
Advantages
Eaton has over 75 years in the capacitor systems business . You can
count on Eaton’s extensive power systems experience to provide
a world-class solution to satisfy any power factor need . Quality
Application description
Utility customers
Metal-enclosed power factor correction systems are fully assembled,
tested, and ready for installation . Very little field assembly is
required . Installation and maintenance costs for metal-enclosed
systems are low compared to pole and rack mounted capacitor
banks . Metal-enclosed systems and detuned filters are less
vulnerable to wildlife and airborne contaminants that can cause
tracking and faults . In addition, metal-enclosed systems significantly
reduce the risks and the associated liability involving arc-flash and
untrained personnel . All live parts are contained in a grounded, key
interlocked enclosure, and no internal hardware is accessible . Metal-
enclosed systems are aesthetically pleasing due to their low profile,
and can be painted to match the surrounding architecture .
are just some of the reasons more and more customers are using
These
metal-enclosed capacitor and detuned filter systems .
Industrial customers
Many industrial power users can take advantage of the benefits
associated with medium-voltage power factor correction . Medium-
voltage solutions usually support the scale and scope of larger
utility services . Medium-voltage applications can be found in the
following types of industries: automotive, pulp and paper, plastics,
petrochemical, and heavy manufacturing . Individual fixed capacitors
provide power factor correction directly at the cause of the problem,
such as large horsepower MV motors . Medium-voltage systems
allow large facilities to correct power factor at or close to the point of
common coupling (PCC), where the utility electrical system meets
theirs .

The savings can be significant in materials, installation costs,
cost-effective alternative to many local low-voltage power factor
correction units .
Commercial customers
Many commercial customers are purchasing power from their
utility at higher voltages today (2 .3–15 kV), and can also take
advantage of medium-voltage power factor correction systems .
These solutions can meet the needs of large office complexes,
hospitals, and universities, among others .

Benefits
Ease of installation
Eaton makes installation easy . All systems are completely assembled
in the factory, with all equipment pre-wired and pre-tested for easy
on-site installation . Only shipping splits must be connected in the
field . Splice kits connect bus systems, and control wiring is easily
connected at each enclosure . Current-limiting fuses, contactor
assemblies, and the incoming switch assembly can be removed
from the enclosure if needed . Line terminals are completely
accessible from the front of the system . Bottom steel barrier at
top of base channel is standard .
Personnel safety

All medium-voltage doors are mechanically interlocked with the
disconnect switch . Key interlocks are provided standard on all
enclosure doors, and can be coordinated with upstream disconnect
devices .

Ease of maintenance
All components are accessible through standard compartment

A viewing window is standard on all compartment doors,
providing visual access to fuse and contactor status .
