Abstract
This paper put forward a new method of multi-frequency sweeping tower grounding resistance measurement in view of the faults of the existing measurements such as low efficiency, low accuracy and limited applicability. The basic principle is to inject adjustable frequency to tower grounding to measure the tower grounding resistance, and to get the accurate tower grounding resistance with the data fitting algorithms. A multi-frequency sweeping measurement model was given, and the influencing factors were analyzed. The range of injected current frequency was confirmed. What's more, a multi-frequency sweeping tower grounding system was constructed to do the experiment. The results show that the method can accurately measure the tower grounding resistance with grounding connected, which has a higher efficiency, accuracy and a better applicability.关键词
