4.3.- CHECKS ONCE THE CAPACITOR BANK HAS BEEN CONNECTED AND THE
REGULATOR
1.- After start-up, make sure that the unit is operating correctly. A sign of proper operation is the
display indicating a cos φ close to 1 and the reactive energy meter should stop (if it is electro-
mechanical) or the blinking light of the indicator LED of the kvar.h/pulse ratio should reduce its
rate.
2.- Check that the power supply voltage does not exceed the nominal value +10%
(IEC 60831-1).
3.- Check the current absorbed by each capacitor.
Under normal conditions, it must be close to the nominal value indicated on its dataplate and
never exceed 1.3 times this value constantly.
Continuous consumption over the nominal value may be caused by the presence of harmonics
in the network or an excessively high power supply voltage. Both circumstances are harmful
for capacitors.
4.- In accordance with the IEC 60831-1 Standard, the capacitor is prepared to operate at the
permanent voltage assigned to it and with an overvoltage of up to 10% for 8 out of every 24
hours.
Check the working temperature of the capacitors after they have been operating
for 24 hours.
The housing must be below 40 ºC.
