Reactive Factor Controller CX plus
81
19.2 Mixed measurement:
The reactive power caused by the transformer is measured by the medium-voltage current
measurement and is also controlled via the connected compensation system.
Procedure:
Connect the measurement of the controller
as shown on the diagram opposite and start
the
automatic
initialisation
(AI)
(SETUP/100/Ai or SETUP/207). The vector
group of the transformer is considered
automatically in the process.
NOTE:
If the automatic initialisation (AI) was not successful (the messages
and
are
shown alternatingly on the display), the phase correction angle must be set manually (SETUP/206).
The connection possibilities for the most common transformer vector groups and the phase correction
angle
to be set are listed in the ANNEX under point “
Connection for mixed measurement
”. If the
phase correction angle was entered, the control must be switched on (SETUP/100/OUt or
SETUP/310) again, because it
was switched off (“OFF”) by the AI.
