Injection unit REX060
GUID-76627CA5-9351-49BB-ABDE-81A939D12BF4 v3
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.
