HARMONIC PROBLEMS IN OFFICE BUILINGS
Computer equipment in office buildings generate
elevated levels of harmonics which cause
important problems in the electrical installation

The triplen harmonics (3rd, 9th...) are
especially harmful as these sum in the neutral
conductor and generate a high neutral current
causing serious failures and damages in the
installation

HARMONIC PROBLEMS IN OFFICE BUILINGS
PROBLEMS
CAUSES

• Malfunctioning and failure in computer equipment
• Overheating of neutral conductors
• Low efficiency and overheating of UPS,
  transformers and cables of the installation
• Tripping of protections without apparent reason
• Interferences in communication networks
• Incremented power consumption

• Low quality electrical energy. Elevated harmonic
  voltage distortion
• Elevated neutral earth voltage
• High harmonic distortion in the current
• Excessive levels of 3rd and 9th harmonics in the
  neutral conductor
• Elevated true RMS current in the phases
• Low power factor due to harmonics
• Elevated losses in the electrical installation

HARMONIC PROBLEMS IN OFFICE BUILINGS
POLYLUX has developed a series of electromagnetic
filters for the elimination of harmonics named
Compensators. These equipments are based on the
cancellation and compensation of magnetic fluxes
COMPENSATORS
A NEW CONCEPT IN HARMONIC FILTERING
The main advantage of the Compensator is the
absence of electronic components and capacitors.
The Compensators are therefore maintenance free,
have an extremely long lifetime compared with
other types of filters and are compatible with
any electrical installation

COMPENSATOR C10D C20D
Elimination of the 3rd, 9th, 15th harmonic
The C20D Compensator provides a very good
cost-filtering relation. It gives a strong
reduction of the triplen harmonics and eliminates
the overload in the neutral conductor and the
high neutral earth voltage

The C22D Compensator offers elevated filtering of
the 3rd, 5th, 7th, 9th, 15th, 17th, 19th
harmonics, solving all problems caused by
harmonics. The C22DC10D is used in combination
with the C20D C10D, each of these supplies 50

COMPENSATOR C25D
Elimination of the 3rd, 9th, 15th harmonic
The C25D Compensator is totally eliminating the
triplen harmonics (3rd, 9th, 15th), avoiding any
type of overload in the neutral as well as a high
neutral-earth voltage produced by harmonics

WITH GALVANIC ISOLATION
Computer equipment
Thanks to its galvanic isolation, the C25D
Compensator represents the ideal solution in case
of a high level of 3rd harmonic voltage.
Additional advantages are reduction of the
electromagnetic disturbances coming from the
supply network, optional voltage adaptation and
the possibility to use independent earths as the
neutral is isolated from the mains

The C25D Compensator is available in two versions
offering different phase shifts (0º and 180º) for
the 5th and 7th harmonic. By combining both
versions, elimination of the 3rd, 5th, 7th, 9th,
15th 17th and 19th is obtained
