3.8.- PARALLEL CONNECTION OF 2 TO 100 ACTIVE FILTERS
The
AFQm
devices can be arranged in parallel to increase the available filtering power.
Up to 100 devices can be arranged in parallel, either of the
30A, 60A
or
100A
models.
In the case of installations with devices in parallel, a device must be defined as the “
master
”,
while all others will have “
slave
” devices functions.
The “
master
” will be responsible for measuring the network parameters, so only the current
transformers will be connected to it. This allows low-power transformers to be used in these
installations, since an individual transformer does not have to be connected to each device.

New device can be connected to existing devices without having to shut down or disconnect
them. This ensures filtering capacity can be increased or degraded device in critical installa
-
tions can be replaced without affecting the installation, allowing connection without shutting
down the device and also making it possible to achieve 0
MTD
(Maximum Tolerable Downtime).
In the event of failure of the “
master
” device, the front connection of the current transformers
allows connection to be changed to a “
slave
” device, reconfigured as the “
master
”, meaning
the system resumes operation quickly with minimum downtime.
