 4.- STATIC CAPACITOR BANK START-UP

       

 4.1.- BEFORE START-UP

The static capacitor banks include a power factor regulator. 

Prior to start-up, the operation of said regulator must be known; for this reason, all capacitor 

banks come with the specific manual of the regulator being used. 

Ensure you have this manual available for the start-up process. 

For the 

OPTIME EMS-C

, the regulator must have a 

Computer Max 6f V12dc

 type, 12 Vdc 

static output control voltage, or equivalent.

Carrying out the adjustment of the regulator incorporated in the capacitor bank, 

and carrying out an optimum start-up, requires that the installation load be at least 

30% or 40% of the nominal load for which the capacitor bank has been sized. 

If all the stages are not arriving, the connection can be done manually to check 

them all.

The  entire  capacitor  bank  should  not  be  connected  manually  during  low  load 

moments, because under certain circumstances it could produce resonance phe-

nomena with the installation's power transformer.

       

 4.2.- START-UP

Apply the safety regulations listed in section “

3.- INSTALLATION

 of this manual 

before operating the units.

The National Electric Code of the country where the capacitor bank is in-

stalled or operated should be strictly followed.

1.-

 Ensure the internal two-pole circuit breaker that starts the regulator (shown in 

Figure 11

) is 

in place.
