8.1.1

Injection unit REX060

The injection unit REX060 is used to inject voltage and current signals to the stator and rotor circuits of
the generator or motor. REX060 generates two square wave signals with different frequencies for
injection into the stator and rotor circuits respectively. The response from the injected voltage and
currents are then measured by the REX060 unit and amplified to a level suitable for the analog voltage
inputs of IED.
For local operation, the REX060 unit is provided with a control panel on the front.
8.1.2

REX060 start up sequence

When the injection unit REX060 is energized, a logotype is shown followed by current REX060 revision
status. When the start up sequence is completed, the main menu (normal display content) is shown. The
duration of the start up sequence is a few seconds.
