Harmonic Filter Banks
fact sheet
• Key interlock system dictates a safe sequence of operation
and entry into capacitor bank
• Blown fuse detection systems offer the highest level of reliability
• Main incoming fuses provide main bus protection and backup
protection for capacitors
• Heavy-duty lightning arresters protect bank from lightning
and switching transients
• Harmonic filter reactors provide the necessary reactance for
tuning the capacitor bank to the desired frequency, as well as
reducing the frequency and magnitude of inrush currents
from back-to-back capacitor bank switching
• Long life and low maintenance vacuum switches control
Product Overview
each stage
GE Metal-Enclosed Medium Voltage Harmonic filter banks are
designed for industrial, utility, and commercial power systems
to improve power factor, reduce harmonic distortion, increase
system capacity, and improve voltage regulation.
• Individual capacitor fusing improves bank reliability and
protects against case-rupture
• Control power transformer is provided for protection, control
and operation of the bank
Virtually any design constraint, provision, or harmonic related
problem can be met. GE can design and guarantee filter systems
to meet IEEE® 519 requirements.
• Ground bus assists in grounding during maintenance
• Automatic capacitor bank controller switches stages based
on current, var load, power factor, temperature, time-of-day,
Standard and custom designs are available for placement in
metering pulses, or voltage
outdoor or indoor substations (an enclosure integrity option can
be added to allow for placement in publicly accessible areas) for
power factor correction, loss reduction, and voltage support.
The banks come fully assembled and ready for interconnection.
• On/off/auto switches allow both automatic and manual
control as necessary
• Enclosure lights in the control, main-incoming fuse, and
capacitor compartments allow easy viewing in nighttime
Features and Benefits
• Load interrupter air disconnect switch provides the
“visible-break” required by NEC
fact sheet
Both indoor and outdoor designs are available with a host of
options and accessories to fit the requirements and desired
configurations of virtually all installations. Single stage and
multi-stage, single tuned or multi-tuned filter banks, with or
without high-pass configurations are available.
GE’s medium voltage harmonic filter banks are designed to be
connected anywhere in the electrical system. Typically, they are
connected at the medium voltage service point between the
utility supply and the customer.
With GE’s Engineering staff, a harmonic filter bank can be
