SVGm IP54

3.8.- PARALLEL CONNECTION OF 2 TO 100 SVGm

The SVGm IP54 devices can be arranged in parallel. Expandable by up to 100 parallel devices of the 67
kvar, 69 kvar and 100 kvar 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 transform-
ers 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 capacity can be increased or degraded device in critical installations 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 re-
sumes operation quickly with minimum downtime.
Note: The 200 kvar (SVGm-3WF-200C), 300 kvar (SVGm-3WF-300C) and 400 kvar (SVGm-3WF-
400C) cabinets are made up of 2, 3 and 4 100 kvar devices in parallel.
