1.- BASIC INSTRUCTIONS
This manual is designed to familiarise the user with operating the FAR-Q power factor
correction and filtering equipment in order to get the best from its features.
FAR-Q hybrid filters are specifically developed for power factor correction on systems
with medium harmonic distortion. The aim is to improve power factor and at the same
time, to attenuate harmonics. The operating principle consists in correcting power factor
and at the same time absorbing the 5th and 7th harmonics generated by certain loads
so that they do not get into the system or go towards other nearby loads.
Please read this manual carefully before connecting and switching on the
instrument in order to avoid irreversible damage caused by improper use.
NOTE: So that absorption is effective the hybrid bank must be separate from the other
loads (other lines or users) by a shock reactor or transformer
1.1.- Checking the contents of your package

1.3.- Safety warnings
This manual contains information and warnings about the FAR-Q hybrid
bank which must be followed to guarantee the proper operation of all
instrument functions and to maintain it in a safe condition.
If the instrument is not installed in accordance with manufacturer's
specifications, the instrument's protection may be damaged.
Check that the protection devices are operating correctly.
2.- MAIN FEATURES
A FAR-Q hybrid filter is formed by various groups of inductances plus a capacitor in
series, located in an appropriate cabinet. Each step is characterised by three
parameters:
1) Power factor to be corrected at 50 or 60 Hz.
2) Harmonic to be filtered, generally 5th and 7th.
------ Absorption filter ------ User Manual, M98206701-03-07A ------ Page 4 of 11------
3) Harmonic current capable of absorbing.
Each step is formed by 2 reactors and a 6 terminal capacitor which contains 2 threephase, 3 terminal capacitors each electrically insulated. The operating principle of this
design is that each reactor is connected to each of the three capacitor terminals forming
an LC set tuned to a frequency close to the 5th harmonic and another set tuned near to
the 7th harmonic. The following diagram shows how the step is formed:

4.- INSTRUCTIONS FOR INSTALLING THE FAR-Q FILTERS
4.1.- Initial checks (before applying voltage)
For the FAR-Q hybrid filters to operate properly the following general installation
conditions must be followed:
• The equipment's ventilation conditions must be examined leaving minimum
distances between the sides and bottom of the cabinet and walls ensuring that air
can circulate properly.
• FAR-Q equipment must not be mounted near to heat sources. The maximum
ambient temperature must not exceed 40 ºC. Assemble ventilation over 35 ºC. In
particular FAR equipment must not be installed in direct sunlight.
• FAR-Q equipment must not be mounted in the same line as any other active filter.
• Check that the equipment's rated voltage stated on the technical features board
matches the rated voltage between phases in the system to which ot will be
connected.
• Check that the equipment setting (step and currents) match the installation's
requirements.
4.2.- Revision of external connections (before applying voltage)
------ Absorption filter ------ User Manual, M98206701-03-07A ------ Page 8 of 11------
All external connections must be via the terminal boards and the input strip on the FARQ cabinet.
- It is necessary to install a current transformer in order to start (normally In / 5 A) in
accordance with the total current of the installed receivers. The current
transformer secondary line must have the appropriate diameter in terms of its
distance from the regulator (minimum 2.5 mm2).
- The power supply voltage for the regulator is between phases (except when it is a
special single-phase regulator). Voltage must be taken from the two phases
where there is no current transformer. The phase where the current transformer
is installed does not coincide with any of the phases from which voltage is being
taken to supply the regulator.
- The current transformer is installed at a point where all of the load currents to be
corrected plus the capacitor current are passing.
CORRECT INCORRECT
CORRECT
The current transformer has to
be in front of the bank and the
receivers (motors, etc).
Fig. 6.- Attaching the current transformer (CT)
T. C.
S1
S2
INCORRECT
- No capacitor will be
connected because the current
transformer does not give any
signal.
- Check that the CT is not
short circuiting or installed
outside the loads.
S1
T. C.
S2
INCORRECT
- All capacitors in the bank are
connected, but do not
disconnect when the load
decreases. Risk of
overcorrecting the system
without a load.
------ Absorption filter ------ User Manual, M98206701-03-07A ------ Page 9 of 11------
Connect the current transformer secondary (S1-S2) onto the terminals marked S1-S2 (1
and 2). If a cos ϕ value appears on the display which does not match, it means that the
phase progress is wrong: invert the connection of the voltage phases on the regulator
(or invert S1-S2 on the current transformer secondary). (See regulator manual)
5.- STARTING-UP OF FAR-Q EQUIPMENT
Follow the steps stated below to start hybrid filter equipment:
1. Check the tightness of the bank's connections.
2. Check if the voltage and frequency levels are correct in the installation.
3. Check that the current transformer is connected on the correct line and that its
polarity, both physical and wiring, are also correct.
4. Check the operation of the regulator without power.
5. Program the regulator in accordance with the instructions in the regulator's
manual.
6. Connect power.
7. Check the capacitor burden.
6.- TROUBLESHOOTING
If this equipment does not work properly when applying voltage, check the following
points:
• If a step does not enter, check the contactor coil and the selector or control relay.
• Check that the step current does not exceed the rated current under normal
operating conditions. A true effective value instrument must be used.
• In the event of a fault, which cannot be resolved using the above paragraphs, please
contact the CIRCUTOR technical service.
IMPORTANT!
• It is recommended that the temperatures of the capacitor walls and the reactor iron
are checked after one hour's operation. The former must not exceed 60ºC and the
latter 85ºC. If not, check the ventilation.
7.- MAINTENANCE
Annual inspection:
• Inspect the bank by eye. No insulation faults or overheating parts should be
detected.
• Check la temperature of the capacitors and reactors (limits stated in paragraph 6).
• Check that the contactor contacts are not showing signs of wear.
• Check that all steps work properly. If not, check voltage supply fuses.
• Check the current in each step. Excess current may be a sign of more harmonics
than the filter can absorb and that it may be necessary to expand the filter.
• Check that there are no power terminals with loose connections which may cause
the cables to overheat.
