rating can be measured when the
monitored system is at 100% of
operating capacity (i.e. at 100% of
system capacity a 5 A CT should
output 3 A).
If the current transformers are
sized so that the percentage of
the output is lower, the loss of
resolution may cause inaccuracies
in the monitoring and control
functions and affect the
functionality of the control.
»A/x«: "/x" shows the relation to
the current range which can be
selected (1 A or 5 A).

Busbar
The busbar parameters in the device are often named with the affix "1". This preparation
is done to avoid confusion e.g., if a model with a second busbar measurement is
introduced.

50 to 650000 V
[400 V]
This value refers to the rated
voltage of busbar 1 and is the
voltage measured on the potential
transformer primary.
If voltage measuring is configured
to 1Ph 3W, the WYE voltage
(VL1N) must be entered here.
The busbar 1 potential
transformer primary voltage is
entered in this parameter. The
busbar rated voltage is used as a
reference figure for all busbar
voltage related functions, which
use a percentage value, like
synchronization.

If the busbar voltage falls below
this percentage of the busbar 1
rated voltage (parameter
), a dead bus condition is
detected and the logical command
variable "02.21 Dead busbar1"
becomes TRUE.
