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.
