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
