2.1.2. CPC2 PANEL: ZERO SWITCHING CONNECTION CONTROL BY TWO SIN-

GLE-PHASE STAGES

The static capacitor banks come equipped with CPC2 panels in the single-phase stages.

The role of the CPC2 panels is to control the zero switching connection of the thyristor-diode

modules that operate the single-phase stages, preventing connection current transients.

The typical connection diagram of a step can be seen in Figure 6 and with more detail in section

“7.- OPTIM HYP type diagram”.

The CPC panels are activated via a 12 Vdc signal supplied by the Computer HYB regulator's

outputs. The standard CPC2 panels are designed to always be used between phase and neu-

tral on networks with phase-neutral voltage of Umax = 254 V.
