5.3.- MAINTENANCE WITH THE CAPACITOR BANK CONNECTED
Check that the main switch turns on and off without having to force the mechanism.
If there is an individual earth leakage protection for the capacitor bank, check its proper
operation by pressing the test button.
Check that the steps connect and disconnect normally, in accordance with the connection
operations carried out by the
Computer HYB regulator.
Check that when the single-phase step is disconnected there is no consumption in the cable
from the unipolar circuit breaker to the capacitor terminal.
If there is consumption this means that some of the thyristors are defective and are short-cir-
cuiting
Check the consumption of the different steps in each phase. The normal values are shown in
, in accordance with the power of each step.

Note: When the consumption of the steps is 25% less than that stated in
and the volt-
age is within the tolerance limits, this is usually a sign of degradation of the capacitors. They
must be replaced with a suitable spare part if this is detected in a step.
Note: When the consumption of the steps is 10% more than the values stated in
may be caused by the presence of resonances. If this is detected, measure the THD of the
network voltage (it should be below 5%).
