• Once the cables are installed, disconnect the jumper connecting terminals S1 and S2 of the
bank (seer Fig. 5-5)
Fig. 5-5.- Jumper for short-circuiting the secondary winding of the current transformer (CT).
Any time you wish to change or disconnect a current transformer that is already
installed, it is important to install the jumper connecting S1 and S2.
6 CAPACITOR BANK START-UP
6.1 Before start-up
The automatic capacitor banks include a power factor regulator. Prior to start-up, the operation of
said regulator must be known; for this reason, all the banks incorporate a specific manual of the
regulator used. Ensure you have this manual available for the start-up process.
In order to carry out the adjustment of the regulator incorporated to the capacitor
bank and carry out an optimum start-up, requires the charge of the installation be
at least 30% or 40% of the nominal charge the bank has been sized for. In the
case that all the stages are not included, they may be manually connected in order
to check them all.
During low charge periods, manually connecting the entire bank is not
recommended, as in some cases resonance with the installation power
transformer could occur.
the capacitors are connected in manual mode, first allow enough time for the
capacitors to discharge (as indicated in the bank's specifications tag) before
reconnecting them to the power grid. Otherwise, they could start-up out of phase
with a voltage of up to 2xU
n
causing destruction of the capacitor.
6.2 Start-up
Safety
Apply the safety regulations listed in section 2 of this manual before operating the
equipment.
The standards and applicable laws of the country where the capacitor bank is
installed or operated should be strictly followed.
