4.- START-UP OF A HYBRID CAPACITOR BANK
4.1.- BEFORE START-UP
Hybrid capacitor banks come with a computer HYB -type power factor regulator and standard
models come with a CVM-MINI-RS485-model power analyzer.
The installation, operation and maintenance of LV units must only be carried out
by authorised installers. LV regulations (Art. 22) specifically define the require-
ments that authorised installers must meet.
For optimal start-up, the load status of the installation must be at least 30%-40%
of the rated load for which the capacitor bank is sized.
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.- Open the door to the unit and make sure that the general quadrupole switch inside the ca-
pacitor bank is open (in OFF position).
2.- Make sure that all the protection circuit breakers for operation and power are open (in O
position, with the lever in the down position).
3.- Check that the 3 bridges that join the 3 S1 and S2 terminals of the current measurement cir-
cuit of the capacitor bank's CVM-MINI-RS485 analyzer are removed (if the unit has this circuit).
4.- Close (put in I position, with the lever in up position) the quadrupole circuit breaker that pro-
vides the auxiliary power supply to the unit, along with the power supply to the Computer HYB
and the CVM-MINI-RS485 (indicated as auxiliary power supply protection) in
Figure 14
).
