transformers, which are directly
connected to the control unit.
1806 SyA. CT primary rated current 2 1 to 32000 A/x
[500 A/x]
The input of the current transformer
ratio is necessary for the indication
and control of the actual monitored
value.
The current transformers ratio should
be selected so that at least 60 % of
the secondary current 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 a󰈠ect the
functionality of the control.
Notes
"..x" is the current (1 A / 5 A) de󰈡ned
by hardware version.
1804 SyB. PT primary rated voltage 2 50 to 650000 V
[400 V]
Some applications may require the
use of potential transformers to
facilitate measuring the voltages to be
monitored. The rating of the primary
side of the potential transformer must
be entered into this parameter.
Notes
If the application does not require
potential transformers (i.e. the
measured voltage is 480 V or less),
then the measured voltage will be
entered into this parameter.
1803 SyB. PT secondary rated voltage 2 50 to 480 V
[400 V]
Some applications may require the
use of potential transformers to
facilitate measuring the mains
voltages. The rating of the secondary
side of the potential transformer must
be entered into this parameter.
If the application does not require
potential transformers (i.e. the
measured voltage is 480 V or less),
then the measured voltage will be
entered into this parameter.
