Abstract In the generator monitoring system, widely use the power transducer to monitor the power of the generator and the load of generator. The internal fault, the grounding fault and the inrush current of the generator etc., these inrush signals can affect the power measure of the power transducer. This paper analyzes the changes of power transducer by short-term Inrush current, and states the processes of the power oscillation. The end of the paper put forward a method of using digital transducer.
