5.- MAINTENANCE
5.1.- SAFETY REGULATIONS
Take the safety regulations listed in section of this manual into account before
operating the units “3.1.- PRELIMINARY RECOMMENDATIONS”
The National Electric Code of the country where the capacitor bank is installed or
operated should be strictly followed.
5.2.- MAINTENANCE WITH THE CAPACITOR BANK DISCONNECTED
5.2.1. BASIC MAINTENANCE PROTOCOL
Monthly:

Visually inspect the capacitors.

Check the protection circuit breakers.

Control the ambient temperature (average of 30 ºC In accordance with IEC 60831 ).

Control the service voltage (especially during moments of low load, it must not exceed
the n10%).
Bi-annually:

Keep the capacitor terminals clean.

Check that the thyristors are not short-circuited.
To do so, check that if you cut the power supply of the regulator there is no current in any
of the capacitor phases.

Check that the capacitor current is not lower than 75% nor greater than 120% of the
nominal value by phase and that there is no phase unbalance greater than 15%.
Annually:

Check the capacity of the capacitors at the different steps.
An indirect verification can be performed by checking that the consumption matches the
value indicated in
Table 8
, with a maximum deviation of ± 10%.

Check the tightening torque of all terminal connections on the different power ele-
ments.

Inspect the fuses.
- Power Circuit : Check the continuity and temperature of the unipolar and three-pole
circuit breakers.
- Control Circuit: Check the continuity and temperature of the quadrupole circuit break-
er.
