Figure 50: Separate analogue inputs for stator STTIPHIZ and rotor
ROTIPHIZ protection
If sufficient number of analog voltage inputs are available in IED, alternative 2
with separate inputs for STTIPHIZ and ROTIPHIZ is recommended.
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 analogue 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 and ROTIPHIZ.
The default parameter settings are used for the pre-processor block.
Note that it is possible to connect two REG670 in parallel to the REX060 injection
unit in order to obtain redundant measurement in two separate IEDs. However, at
commissioning both REG670 IEDs must be connected during calibration procedure.
It is of outmost importance that REX060, REX061 and REX062
chassis are all solidly grounded. Grounding (PE), protective earth is
a separate 4 mm screw terminal, as a part of the metallic chassis.
