Figure 157: Connection to IED with two analogue voltage inputs
Some settings are required for the analog voltage inputs. Set the voltage ratio for the
inputs to 1/1, for example, VTSecx = 100 V VTPrimx = 0.1 kV
The analog inputs are linked to a pre-processor block in the Signal Matrix Tool. This
pre-processor block must have the same cycle time, 8 ms, as the function blocks for
STTIPHIZ (64S) and ROTIPHIZ (64R).
The default parameter settings are used for the pre-processor block.
It is possible to connect two REG670 IEDs in parallel to the REX060 injection unit in
order to obtain redundant measurement in the two IEDs. However, at commissioning,
both IEDs must be connected during the calibration procedure.
It is important that REX060, REX061 and REX062 chassis are solidly
grounded. Protective ground is a separate
0.15” screw terminal that is a
part of the metallic chassis.
Avoid touching the enclosure of the coupling capacitor REX061 unit
and the shunt resistor REX062 unit. The surface may be hot during
normal operation. The temperature can rise 50°C in REX061 and 65°C
in REX062 above the ambient temperature.
