FIXED CAPACITOR BANKS

The Power Factor Compensation of the MV/LV power transformers is always suggested, since they needs, during the low loads conditions, of a low PF energy.

Power transformers are devided in two types; oil transfomers, and resin transformers.

Italfarad proposes different types of fixed capacitor banks

FIXED CAPACITOR BANKS

Capacitor banks are realized by single phase capacitors, with delta connection, in metal case, provided with overpressure device protection, in compliance with the EN60831-1/2.
