Set the voltage ratio for theinputs to 1/1, for example, VTSecx = 100 V VTPrimx = 0.1 kVThe analog inputs are linked to a pre-processor block in the Signal Matrix Tool. Thispre-processor block must have the same cycle time, 8 ms, as the function blocks forSTTIPHIZ and ROTIPHIZ.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 inorder 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 solidlyearthed. Protective earth is a separate 4 mm screw terminal that is apart of the metallic chassis.8.7.3.3 Settings for sensitive rotor earth fault protection,ROTIPHIZOperation to be set On to activate the sensitive rotor earth-fault protectionRTrip is the resistance level,set directly in primary Ohms, for activation of the trip-function.RAlarm is the resistance level, set directly in primary Ohms, for activation of thealarm-function.1MRK 502 071-UEN - Section 8Impedance protectionGenerator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 297Application manual
